O článku:
This paper describes a numerical simulation model of motion of
moonlets in binary and multiple asteroid systems. Gravitational
accelerations produced by the primary body, its moonlets, the Sun, the Moon,
and eight major planets are accounted for in this model. The asymmetry of
the primary and the effects of solar radiation pressure on the moons in
asteroid systems are also factored in. To run the numerical simulation, we
adopted the orbital state vectors of celestial bodies from the numerical
theory. Using Keplerian orbital elements of the primaries of asteroid
systems, we determined their heliocentric positions. Differential equations
of motion of celestial bodies in asteroid systems were solved in the
asteroid-centric Cartesian reference frame by the Everhart 15th-order method
of integration. The verification and validation of the simulation model
have been performed for three asteroid systems, namely (136617) 1994 CC and
(87) Sylvia, which belong to the near-Earth and main belt populations,
respectively, and (136108) Haumea, which is a trans-Neptunian object. These
are three asteroid systems of almost 300 small Solar-system bodies with
discovered moons which are known to date. All six Keplerian orbital
elements determined with reasonable accuracy are available for all asteroid
moons.
