Statistical Properties of Encounters among Asteroids: A New, General Purpose, Formalism

Icarus, 1998
Abstract The statistical properties of asteroid mutual encounters have been studied by several authors, with the main purpose of estimating collisional rates (and thus mean collisional lifetimes) and the distribution of encounter velocities. In this paper we present a new approach, conceptually not really different with respect to the classical ones,

Automated Computation of General Perturbations for the Flora Asteroidal Group

Publications of the Astronomical Society of Australia, 1991
AbstractThe general perturbations of the asteroids of the Flora group (975″ < n < 1150″, n - the mean daily motion) due to Jupiter have been automatically computed on an IBM 4341 computer with the Hansen method by manipulating Broucke’s Symbolic Poisson Series Processor, and the results have been compared with that computed previously with the ...

Satellite Dynamics About Asteroids: Computing Poincaré Maps for the General Case

, 1999
The study of orbital dynamics of spacecraft about non-spherical bodies has usually been restricted to the “planetary” case where the body is close to an oblate spheroid, with only a relatively small degree of equatorial ellipticity. When investigating spacecraft dynamics about asteroids, the situation is drastically different as the asteroid shape is ...

SinGAN-Based Asteroid Surface Image Generation

Journal of Database Management, 2021
While it is risky considering spacecraft constraints and unknown environment on asteroid, surface sampling is an important technique for asteroid exploration. One of the sample return missions is to seek an optimal landing site, which may be in hazardous terrain.
