Abstract:
By means of numerical simulation of the rotational dynamics of the asteroid (99942)Apophis, the perturbations occurring in the rotational motion of asteroids during their close approaches to the Earth are studied. It has been established that such events can lead to significant changes in the asteroid's own rotation velocity and the orientation of its rotation axis in space. The dependences of the change in the period of rotation of the asteroid on the parameters of the orbit and its rotational state before approaching the Earth are studied. It is shown that disturbances in the rotational moti

Abstract:
Estimates of the influence of the solar radiation pressure and the Yarkovsky effect on the long-term orbital dynamics are obtained for a number of asteroids experiencing successive approaches to planets. Based on the estimates of the change in the value of the asteroid’s proper rotation period obtained in (Melnikov, 2022) due to its approaches to the planets, the influence of such events on the further orbital dynamics of an asteroid through the Yarkovsky effect is considered. It is shown that close encounters with the planets of small asteroids (tens of meters in diameter) with fast rotation

In this paper, the basic classification of asteroids and the history and current situation of asteroid exploration are introduced. Furthermore, some recent research progress on the orbital dynamics of asteroids, including models of the gravitational potential field, the dynamics near asteroids, hopping motion on the surface, and bifurcations under varying external parameters, is reviewed. In the meanwhile, the future research development such as the configuration and evolution of binary or triple asteroid systems and near-Earth asteroid defense is briefly discussed.

AbstractPrevious discussions of the origin of the zodiacal cloud have attempted to distinguish between an asteroidal and a cometary source on the basis of collisional dynamics, that is, by calculating the rates of production and destruction of particles from the two possible sources. The uncertainties in these calculations are too large to permit a useful conclusion. The recognition that the solar system dust bands discovered by IRAS are probably produced by the gradual comminution of the asteroids in the major Hirayama asteroid families may allow us to estimate, with comparative confidence, t

The motion of the Trojans is considered in the framework of the three-dimensional elliptic restricted three-body problem of the Sun-Jupiter-asteroid system including also the secular changes of Jupiter's orbital eccentricity and the apsidal motion of Jupiter's elliptic orbit. An asymptotic solution is derived, by applying the multiple-timescale method, for the cylindrical coordinates of the asteriods and for the perturbations of the orbital elements.

In such a model, the response is approximated as an inelastic collision in which the projectile pushes the ‘rubble pile’ parts of the asteroid together to form a mostly solidified plug in the crater during the sudden impact on the asteroid’s surface.

The Yarkovsky effect is an important force to consider in order to understand the long-term dynamics of asteroids.

The main asteroid belt spans ~2-4 AU in heliocentric distance and is sparsely populated by rocky debris. The dynamical structure of the main belt records clues to past events in solar system history. Evidence from the structure of the Kuiper belt, an icy debris belt beyond Neptune, suggests that the giant planets were born in a more compact configuration and later experienced planetesimal-driven planet migration. Giant planet migration caused both mean motion and secular resonances to sweep across the main asteroid belt, raising the eccentricity of asteroids into planet-crossing orbits and d

Abstract:
<p>The dynamical evolution of the spin axis direction due to gravitational and thermal factors is examined. It is found that the spin axis variations generally are regular and relatively small for the bodies in the asteroid main belt. There are also reasons to believe that this is the case for minor objects beyond the main belt. However, it is found that these regular variations are larger when the orbital inclination of the objects is increased. This effect may explain certain features in the spin vector distribution of the main belt asteroids, not possible to explain by collisional factors.
