The year of 1986 is the Halley comet year. The history of
cometology retained the following curious case. In 1910, when its (i.e. the Halley cometТs) previous visit to the Sun took place, one of the March numbers
of a newspaper УGolos SamaryФ (УThe Voice of SamaraФ) reported, that a certain monk sold shrewdly at the central city square the leaves of УCharm against
meeting with Halley cometФ of the following content: УYou are devil! Satan! Never world Velzewool! DonТt feign you are a celestial star! DonТt deceive the
Orthodoxes, hide your godless tail, because the GodТs stars have no tailsЕDip your tail into fiery river, let it reduce to ashes, let it char, let it fry!
EtcЕФ This curiosity was reprinted by УRusskiye VedomostiФ (УRussian RegistersФ) on the 3-rd of April, 1910 and went down in the history of the
It is interesting to note, that the next visit of the Halley comet was in 1986 and coincided with the 400th anniversary of the city of Kuibyshev
(formerly and now afresh - SAMARA! Ц rem. A.G.).
The author of this article, living in Kuibyshev, dedicated to this
significant date the application for the discovery УComets formation phenomenonФ [1,2], which, as the author considers, convincingly confirms and at
last resolves a so-called comet problem.
2. EXISTING VIEWS (HYPOTHESES) ON THE COMETS FORMATION MECHANISM
In accordance with the views, which were shared by the most part of the astronomers before the experiment УVegaФ (УVenus-HalleyФ), the comets
originate from the so-called comet cloud of Oort and consist basically of dirty ice .
This hypothesis cannot convincingly explain the fact why the comets are grouped around the major planets of the Solar system (in families of
planet-giants). Besides, the mechanism of comets breaking-away from the Oort cloud is actually very unconvincing.
The Nemesida hypothesis (the dwarfish star Ц the satellite of the Sun) did not save the situation.
The second basic hypothesis (S.K.Vsehswiatsky) states, that the comets are the result of volcanism on the major planets or their satellites.
Yet itТs obvious, that this mechanism demandes too high initial speed.
The basic hypothesis now, after the experiment УVegaФ, is the idea
that the asteroids are dead comets. The author considers this point of view as an intermediate stage on the way to the truth.
3. A CONCRETE COMETS FORMATION MECHANISM
The basic authorТs idea is the following: УThe comets are formed
from asteroids as the result of asteroids piercing through the rings of the major planets of the Solar systemФ.
Indeed, it is known that the planets of the Solar system can be collided with small space bodies including asteroids. The major planets
(Jupiter, Saturn, Uranus, probably, Neptune) are surrounded by rings consisting of separate particles. The rings can also be subjected to collisions
with asteroids because they are not the exception in this sense. During these collisions the rings may be pierced through because they are not very dense.
For instance, the thickness of the Saturn ring is about 2-5 km, moreover the stars can be viewed through them. A typical size of the particles
is about 1 cm (in accordance with the data of УPioneer-11Ф).
It is interesting to note, that the space apparatus УVoyagerФ
discovered the two Saturn satellites in the ring system, moreover, one of them is moving in the ring, but the other has a slightly slanting orbit and
therefore it finds itself either at one or the other side periodically. This circumstance confirms the possibility of piercing of the ring. The destruction
of both the ring particles and asteroid and the distribution spectrum of the particles by speed will take place as a result of the piercing of the ring by
asteroid as strong as the concrete circumstances allow. Besides the asteroid flown through the ring takes off some quantity of its substance. The small
fragments of this collision can generate the meteor flows afterwards.
A basic part of the asteroid (a big УpieceФ) will be soiled by the
ring substance and, actually, this very part forms the comet. Indeed, the chemical composition of comet tails and major planets rings are remarkably
similar: H2O (ice, snow, steam), different frozen gases and other volatile components (to the point, the Saturn rings are localized inside the RocheТs
sphere for a liquid body).
The above-mentioned mechanism makes clear and obvious the fact,
that the periodical comets (i.e. by the type of orbits Ц orbit classification in families) are conventionally grouped around the major planets having the
The Jupiter ring is less dense than Saturn rings and it probably consists of snow and gas. This partially explains the fact, that the most of
short-period comets (Jupiterian family) have a faint tail or only have a coma (here it is necessary to take into consideration the rapid evolution, as far as
the period is short enough).
A periodical variations of glitter of the Donati and Halley (with
52-hour period) comets are explained by the fact, that monolithic nucleus of these comets has an asymmetrical stretching form and accomplishes the rotary
motion. This rotation may be the result of collision with the particles of the ring.
A basic mass component of a comet nucleus is determined by the type
of motherТs asteroid: stony, iron-stony, ferrous.
The facts of the division of some comet nuclei may be explained by
the presence of cracks in the nucleus (it may be the result of the collision with the ring). It may lead to the thermodeformation in the vicinity of the
The orbits of the most part of comets lie in the ecliptic plane or near it, although the orbits of separate comets are precessing. This
circumstance is normal in the proposed mechanism frames.
Let us value the frequency of the comets rise. Let us take the
In the current century (here Ц in the 20th century Ц rem. A.G.) the next coarse enough meteorites fell to the Earth (on the land): Tungus in 1908,
Sihote-Alin in 1947, Fenes-County in 1948, and some others. Adopting that the water surface of the Earth is more, than thrice larger that of the land, we
suppose, that about 15 coarse meteorite fell onto the Earth in this century. Considering that the radius of our planet is nearly equal to 6370 km, we shall
get, that on each 2.7.106 km2 of the transverse section area of the Earth (i.e. the ball) may be one collision with a space body in century. The outside
diameter of the Saturn rings is nearly 2.74.105 km and the width of the rings is 5 times as great as the Earth diameter, hence, the Saturn rings area is
equal to ~ 4.2.1010 km2. Considering the relative frequency (on the unit of the transverse section area) of the collisions of Saturn rings with small space
bodies (with asteroids) equal to the that of the Earth, and also considering that the probability of the hit into the flat disk from the free direction is
half as much as that of a ball of the same transverse section area, itТs possible to get the value of nearly 7800 collisions in a century (i.e. every
week!). As a result of this collisions the ring may be pierced and the comet is formed. Still in this calculation was not taken into consideration the
gravitation and screening influence of planet-giant itself, the influence of the mutual speed of collisions, the finite thickness of the rings and the angle
of interaction, the sizes and mass of the asteroid and the particles of the ring, etc., so the real frequency of the comet forming will be less, than it is
calculated. Considering the real value even 10 times less, weТll see, that the figure still remaines big enough (we discover not more than 10-20 comets every
year as average this refer to all the families taken together).
The best criterium of the truth is the experiment. The author
considers that the space experiment УVega Ц JiottoФ shiningly confirms his hypothesis. Indeed, it turned out that the nucleus is monolithic and it has the
asymmetrical form, it is darker, than it was supposed from the УiceФ hypothesis. Still the concrete analisis of the results will be given in the
4. A CRITICISM OF THE REALIZATION OF THE EXPERIMENT УVEGAФ AND THE INTERPRETATION OF ITS RESULTS, GIVEN BY THE ISR OF THE AS OF THE USSR
(Remarks: - This chapter is, basically, the co-name authorТs article of 20.03.86
About 150 soviet organization and enterprises took part in the creation of the station УVegaФ . The considerable forces and means were
taken for the experiment carrying out. It may seeme, that the experiment have passed successfully, the unique data have been received about the structure of
comet nucleus. Still, the author of these lines does not agree with a such synonymous appreciation, although he doesnТt deny the fact, that there really
as received some unique information.
Even more, than a year ago before the peak of the events of the
experiment УVegaФ, the author formulated and argumentally substantiated the hypothesis about comets forming in the result of piercing the rings of the
planet-giants of Solar system by asteroids. This hypothesis was prevented to the ISR and other organizations. Unfortunately the hypothesis has not been
considered at the ISR and author received only formal letters.
Comrades from the ISR adopted the ice nucleus comet (with soils)
hypothesis among their weapons, as a dogma, which, ostensibly, was shiningly confirmed by the experiment. In accordance with this hypothesis, the ice comet
nucleus must gush out great quantities of steam and dust, that was reflected on the experiment itself: the minimum distance from the nucleus at which the both
УVegaФ apparatuses passed by, was intentionally chose within the limits of 8-9 thou km, although the actual precision of pointing was not worse than 1500 km.
Only apparatus УJiottoФ (although not without the aid of the УVegasФ) passed closely to the nucleus and showed the features of a relief: hills, craters.
In conformity with the author hypothesis the comet nucleus must be monolithic: stony, iron-stony, ferrous Ц by the type of motherТs asteroid.
Gases, given off by nucleus under the Solar heating, - are the result of absorbtion and adsobtion the gases and other volatile components, composing the
particles of the rings of major-planets. Thus, the ejections from the comet nucleus (УsoiledФ asteroid) must be comparatively small. To the point, it is
confirmed by the data of apparatus УICEФ (ex УISEE-3Ф), which passed through the tail of Jacobini-Cinner comet on 11 September 1985 (before the peak of the
experiment УVegaФ) the distance of 7850 km from the nucleus and which fixed an unexpectedly small density of the dust [5,6]. The experiment with the station
УVega-1Ф showed, that dust density is significantly less, than it was predicted by the УiceФ model of the nucleus. In connection with this circumstance author
sent a telegram at the ISR. The mistake may be corrected, inasmuch as also УVega-2Ф took place and it trajectory may be improved so that photos would
qualitative really, still it is no happenedЕ
But, after all, strictly speaking, even if both УVegasФ would be
directed straight to the nucleus (with the accuracy of aiming equal to 1500 km all the same the result would be negative: they wouldnТt hit the aim!) and on
approaching to it they would be put out of order but still the task of the stations would be fulfilled as far as the information was transferred to the Earth in
the real time. Nowadays the capacity for work of the two stations are no longer of any importance because the unique chance has been lostЕ There were two
УVegasФ and each of them passed by the comet nucleus at the distance of 8-9 thousands km! It may be compared with the situation when the volcano eruption
taking place at the Kamtchatka is observed from Moscow. It at least УVega-2Ф approached closer to the nucleus then it would be possible to excuse the
ambiguities and sheer blunder of the type: УThe Halley-comet has a double nucleus?!Ф or УЕit seems that the nucleus has no clear boundaries, - it is
similar to a boiling potФ  Ц according to the data of УVega-1Ф. In  the following figures are offered: the time error of the meeting with the nucleus
is 10-20 s, a relative velocity of the approach of SA (space apparatus) to the comet is less than 80 km/s. Consequently, the possible error of the two УVegasФ
aiming (multiply these figures) is not more than 1.5 thousand km. Why was it necessary to fulfil such a senseless double? And who was interested in it?
However, it was proudly declared that both of the stations are keeping their capacity for work and now the objects in Universe are searched
that might be studied by the УVegasФ. Still, this declaration sounds as no more than an attempt to appologise their own mistakes (but to-day we donТt hear much
about these searches). Let us wish the ISR sucsess as far as the area of the searches is very wide: the whole boundless space!
Probably the author is a little bit exaggerating, on the photos of УVega-2Ф something is seen and this was shown for first time by TV USSR on the
24th of April, 1986 (after the program УVremyaФ (УTimeФ)), but in this very TV-program a sacramental statement was formulated: the comet nucleus is a dark,
coal-like body having the coefficient of reflection comparable with that of asteroids! But you see, the author of this paper expressed his opinion on this point
even more definitely more than a year ago! My first letter to the ISR was sent on the 20th of February, 1985! Then at the same TV-program an incorrect
conclusion was heard about that the comet nucleus was still icy. The same very thesis was formulated by Academician R.Z.Sagdeyev in [9, p.88]: УЕthe
hypothesis according to which the comet nucleus is an enormous block of УdirtyФ ice of an irregular form has been confirmedЕIts surface is covered by a crust
of some refractory material having the thickness of about a centimeter Ц the composition of this material is being specifiedФ. The thesis is repeated with a
really enviable persistence! R.Z.Sagdeyev is echoed by Professor V.I. Moroz the author of the so-called nucleus model in the form of a УMarch snow-driftФ
[10,11] that at first sight seems to be convincing. But this is at first sight only! The case is that this model is not in principle able-bodied! Though I had
no chache to pick the nucleus of the Halley comet with my finger still I declare that the comparison of the comet nucleus with the March snow-drift is
erroneous because of quite different physical condition. We know that specks of dust and mud donТt fly away from the snow-drift due to the gravitation, and the
Halley comet nucleus has practically no gravitation influence, as far as its mass is too small. Add to this the pressure of vapours being formed and
dilating into vacuumЕ Under such circumstances even the crust of porous platinum would not keep at the surface for any considerable period of time, to
say nothing of the impossibility of the process of the crust growth resulting in its self-renewal, i.e. the УMarch snow-driftФ model that was widely
advertised in disabled and groundless in principle!
Basing on the theory of the icy nucleus it is difficult to explain
the hills and craters at the surface discovered by УJiottoФ, not by the УVegasФ, as far as the melting of ice leads to the smoothing of УwoundsФ (Mr.
B.A.Vorontsov-Veliaminov is of the opinion that craters are percussive formations).
Probably, R.Z.Sagdeyev and his colleagues being the focus of
attention of the press and taking a great interest in giving away autographs were too busy and had no time not only to analyse the
materials which I sent them but even to go deep into their own statements. Let us recall the situation around the experiment УVegaФ: at first there were a lot
of advertising in the press, by radio and TV, then the experiment itself was carried out and were promised that the results were to be published soon. Now
the racket has been finally faded and it turns out that to Уprocess the obtained materialФ requires a considerable time (more than a year) and the
results will be published in special journals. And nowadays our attention is switched over to the project УPhobosФ (УFobosФ) (writed in 1986 - Rem.
A.G.). As for the Halley comet, it turns out that the answer to all the questions might be finally given probably only in 76 years when its next
visit to the Sun takes place and weТll have at our disposal different technical possibilities - such a УregretФ was expressed by the Academician
R.Z.Sagdeyev (wasnТt it done so that not to return any longer to this an unpleasant for him questions?). I am afraid that this УregretФ is simulated.
Still I suppose that tens of millions of roubles were not wasted only for the sake of vague knowledge?
However, it is interesting to note that in  R.Z.Sagdeyev writes: УЕthe inevitability of the objective tendency doesnТt diminish our
responsibility before this (i.e. communist Ц A.G.) futureЕФ. Here undoubtedly Acad. R.Z.Sagdeyev is right. I would like to remind of that the USA are
planning to realize their projects УAsteroid FliebyФ and УCometТs RendezvousФ earlier than in 76 years Ц and the USSR may lose its priority in the science of
A comet nucleus reflects approximately 4% of the incident light , so it may be conclude that it is a black body of a good quality! And it
was really difficult to call it icy.
In  R.Z.Sagdeyev revealed a turn in his views that is
unexpected enough, the academician writes: УOutwardly it (i.e. the object Ц A.G.) is somewhat like MarsТs satellites - Phobos and Daimos (the УPhobosФ Ц
project is in prospect with R.Z.Sagdeyev (in 1986) Ц here is a sound logical connection for you! Ц A.G.) but still more similar analogues may be some small
satellites of Saturn and Uranus. This keeps within the frames of the hypothesis (I wonder, which and whose? As far as before this there was said a lot of
nonsense about the cloud of Oort, Nemesida, etc. Ц A.G.), assuming, that comet nuclei were formed comparatively not far from the Sun, approximately at the
placewhere the major planets are located Ц from Jupiter to Neptune, and then were thrown off at a greater distance during the formation of these planetsФ
(underlined by A.G.). Any explanation is needlessЕ For Academician R.Z.Sagdeyev it remains nothing but to wait a little more and to pronounce quite a fatal
phrase: УIt seems to me that comet nuclei were generated out of asteroids while the latter were punching the rings of the major planets of the Solar systemЕФ Ц
i.e. to read at last the formula of my discovery.
In  we were told that during the УVegaФ Ц experiment the amount
of steam lost by the comet nucleus every second was measured for the first time. And the figure of tens of tons was cited. It would be interesting to know
in what way this figure was obtained as far as there were no direct measurements of this index (for this purpose it would be ideal to place
the comet nucleus into a sack!). However the author of this paper having at his disposal such values as the cross section of the nucleus, integral flow of the
solar energy per unit of the area (i.e. solar constant taking into account the distance from the Sun) has determined the amount of water that may be heated
from 3oK (the temperature of the cosmic background) up to the vaporous condition (with the account of all the phase transfers) per 1 second and has
obtained the figure of the same order that in , assuming that ice is a black body (Kabs = 0.96). It means that this figure was simply calculated in ISR on
the basis of their faulse model, i.e. the desirable was claimed as real.
The apparatus УJiottoФ revealed the jet escaping of gas (vapours).
The intensity in jets may not be higher than the physical limit caused by the ideal conditions of the solar heating (as far as the nucleus is not a gas-bag)
and also by the accepted physical model (let it be even a black icy nucleus), consequently, the intensity out of the jet is much lower than the
physical limit and the total loss of the nucleus mass in the form of vapour is in any case considerably lower than the figure mentioned in  and which
representing the physical limit. Besides, it is known that the Halley-comet nucleus is rotating and one side of it is more active  and consequently the
other is on the contrary less active. This circumstance reinforces the Уactivity contrastФ and lowers the index. Thus the figure of 40 tons of the
vapour lost by the comet per one second is exaggerated (and not by the order!), and if to take into account my hypothesis (i.e. the nucleus is the asteroid in
its basis) it is exaggerated still more. The УVegaФ Ц apparatuses passed at a great relative velocity (~ 80 km/s) by the Halley comet nucleus thus creating
their own blast, the amount of the registered dust and gas is to be distributed over a lot of kilometers of the trajectory; the dust and gas in their basic
part may fly together with the comet and break off from it not so fast as it may seem Ц taking account of all the forces and factors (many of them though
weak act in great scales) may lead to an unusual result.
Note that the fact consisting in that one side is more active than
the other substantially confirms the mechanism of the comets formation as the result of punching the rings of the major planets of the Solar system by
asteroids (see the materials of the application for the discovery), as far as the time of punching the ring by an asteroid (<1 s) is not sufficient for
the asteroid to swing significantly. The porosity of coaly hondrites, for instance (and as hondrites may serve asteroids and also, in particular, the
nucleus of the Halley-comet) may reach the value of more than 20% , that may promote a significant adsorption and absorption of volatile components
which the ring contains. You should not forget that the punching of the ring (the layer of small bodies of the finite thickness and some average density) by
a large asteroid is the process of a successive interaction of a massive monolithic body of irregular form with a great number of small bodies during a
certain time interval. In this case as the evaporation of the colliding bodies is going on the shock wave will be growing УsmoothlyФ enough and exerting its
influence for a long time. In general, the physics of such an interaction differes from the physics of the stroke of two solid bodies commensurable with
each other and is of interest as the object of a separate investigation both theoretical and experimental. It is obvious, however, that this circumstance
may promote the capture of the volatile components of the ring.
And now some remarks in respect of the photoes made by the
УVegasФ apparatuses. In  Academician R.Z.Sagdeyev says that: УPowerful dust rejections are slightly camouflaging the nucleus surface
but a detailed photometrical treatment allowed to determine its form, dimensions and reflecting abilityФ. However thereТs no statement that they
succeeded is seeing the nucleus surface itself. ThereТs no doubt that the averaging of images, space filtering, etc., may УemphasizeФ something but they
are not able to УextractФ the information that is absent in the initial image. In this connection the statement that the images of the comet
nucleus proper were obtained is not quiet correct. Incorrect and groundless is also the statement about that У...in comets... the material of
which the Solar system was generated is preserved in its original formФ . Comets occur and die nowadays with the probability which estimated
After the УVegaФ experiment a number of new hypotheses of the comet formation appeared, but they donТt resolve all the contradiction in
contrast to that offered by the author. At present the major part of specialists suppose that asteroids are dead comets (those left after the
melting of ice - the main component). This point of view is an intermediate one, as far as it would be more correct to say: some asteroids are
dead comets (the main component of the comet mass is the asteroid proper).
The basic arguments were formulated by the author as far back as
the beginning of 1985 and were expressed in the letters, besides in 1986 they found their reflection in the materials of the Application. At present
these materials may be only supplemented in the light of the new experimental facts and data.
The potent aspects of the hypothesis are:
- its concrete character and the absence of any obstacles for the further
concretization; absence of any abstractions of the type comet cloud of Oort, Nemesida, etc., that were seen by nobody;
- logical inevitability of the offered mechanism, caused by the absence of physical interdictions and the finite value of the probability of the event;
- possibility of a versatile verification;
- logical connection with all the available facts.
Besides, the hypothesis at the same time gives a harmonious picture of such a phenomenon as the УTungus meteoriteФ (appendix to the Application,
here chapter 6), that in general agrees with new views on this phenomenon  and removes any misticism and mystery, created around this sensational
5. TERMINOLOGY AND EXCEPTION TO THE RULE
If the term УcometФ implies a small celestial body with a gaseous
cover (coma) or tail consisting of gas and dust that is probably more concrete than a vague meaning of this word given in dictionaries, then the author
proposes to call the comets formed as result of piercimg of the major planets of the Solar system by asteroids to call these comets Уsamaroid(s)Ф - in honour
of the city of Samara which in 1986 celebrated its 400th anniversary (that was also the year of the Halley-comet). As it follows from the introduction to this
article this name УsamaroidФ is quite justified.
For the comets formed as a result of an asteroid passing along the
trajectory close to the tangent through the atmosphere of such planets as the Earth, Mars and Venus (the Earth group) - it is known at least one case when a
bolide (fire-ball) entered the atmosphere of the Earth, passed it through and then again went away beyond the limits of the atmosphere and at this
it didnТt become the Earth satellite - the author proposes the name (or term) УnovidФ. Though the probability of the formation of weak comets is such a
way is almost zero, still it should not be fully excluded out of the sphere of our attention. After the contact with the atmosphere any celestial
body takes away with it a portion of gases. Even SA - artificial Earth satellites have their own atmosphere. The term УnovidФ descend from the name of
a small and very picturesque village УNovinkyФ situated in the Zhiguli mountains near the city of Samara within the area of the first national park in
Russia (not 1st in the USSR) УSamarskaya LukaФ.
The two terms proposed by the author symbolize the unity of great
and small in the Universe...
For the comets out of the cloud Oort (let it be so! - the author is
just enough) the author offers the term УOortidesФ. - Let the Time to prove the vitality of these names.
Thus, the Уcosmic bulldozerФ - the Halley-comet is, apparently, a ferrous-stony УsamaroidФ belonging to the Neptune (or Uranus?) family.
6. TUNGUS PHENOMENON
One of the arguments against the proposed mechanism of the comet
formation may be a false interpretation of the event that took place in 1908 and is known under the name УTungus meteoriteФ as far as the zone of fall
was of an unusual character; the meteorite proper was not found. In this connection a great number of hypotheses appeared on the collision of the Earth
and the icy comet that later on evaporated. But as far as the comet is no more than a Уdirty asteroidФ and is not a very original one as for the results of
its influence then the author offers the following non-contradictory explanation of the event (without any pretension on originality).
At 8 oТclock a.m. on the 30th of June, 1908, in the Tungus taiga the event took place known under the name of УTungus meteoriteФ.
The examination of the place of the Tungus meteorite fall in 1927 and later on showed the absence of the meteor body and craters. The woods
within the radius of 30 km was brought down by the blast [17, p.54]. All these in total was unlike a usual fall of meteorite.
Take notice of several facts.
After the fall of Sihote-Alin meteorite in 1947 numerous splinters
were found. On having analysed these splinters a soviet scientist E.L.Krinov marked out conditionally three stages of the meteorite splintering into
composing parts by a number of characteristic signs [17, p.42].
At the Tungus meteorite fall an unusual phenomenon was observed: at
the vast territory to the west of the place of the meteorite fall the night from the 30th of June to the 1st of July practically did not set in [17, p.53].
The sky was light and even in England it was possible to read a paper at this time (this phenomenon is, apparently, belonging to the type of УcrepuscularФ
ones as far as this season the Sun sets not far beyond the horizon and the diffusion of Solar light may occur in the upper layers on fine-dispersed
particles). At the same time to the east of the place of the meteorite fall there was nothing of the kind. This circumstance substantially confirms the
assumption that the trajectory of the Tungus meteorite fall was close to the tangent to the Earth surface, i.e. the meteorite entered the atmosphere of the
Earth at the small angle to the horizon. At such a trajectory the meteorite must move significantly longer in the Earth atmosphere, experiencing
at this its resistance and being subjected to destruction. Thus, there are all the grounds to suppose that the number of stages of destruction of the Tungus
meteorite was more than that of the Sihote-Alin meteorite (mentioned above) and on approaching to the place of its fall the Tungus meteorite was almost
completely destroyed to small splinters, forming a kind of a cloud consisting of stony hail or УrainФ if the body was melted in addition. On collision
of this cloud with the Earth surface a powerful blast must be generated over a great area and in fact this phenomenon took place in case of the Tungus
meteorite. Besides, recently in the region of the explosion the microscopic balls were discovered. These balls were not of the earthly nature [17, p.55].
Thus, the Tungus meteorite is a small cosmic-body entered the Earth atmosphere by the trajectory close to the tangent and consequently subjected to the full
