Regoliths on Small Bodies in the Solar System
Annual Review of Earth and Planetary Sciences, 1982A regolith is defined as a layer or mantle of loose, incoherent, rocky material of whatever origin, that nearly everywhere forms the surface of the land and rests on coherent bedrock. The regoliths on many planetary bodies are the result of continual impacts, which transform coherent surfaces into fragmental debris.

Number of minor planets having well-determined orbits, cataloged by permanent designations (numbers) as of 1998, January 1: 8125. Number of known minor planets having less well-determined orbits, cataloged by provisional designations: > 25, 000. Most are located in the Main-belt, between Mars and Jupiter. Semimajor axis, range 2.06 to 3.28 AU, mean a =

Sample return from small solar system bodies
Advances in Space Research, 2000Abstract With plans for multiple sample return missions in the next decade, NASA requested guidance from the National Research Council's SSB on how to treat samples returned from solar system bodies such as planetary satellites, asteroids and comets. A special Task Group assessed the potential for a living entity to be included in return samples from

Small Bodies of the Solar System
International Astronomical Union Colloquium, 1984Schmidt telescopes are ideal for many types of survey work, and this includes surveying the solar system. Schmidt cameras have the advantages of speed and wide fields for rapid coverage of large areas of the sky, and good image quality over the entire field. The small focal ratios also have the effect of enhancing low surface-brightness features.

Small bodies of the Solar System
Nature, 2000Discoveries of comets that behave like asteroids and asteroids that behave like comets are making us reassess our view of Earth's smallest neighbours.

Shape of small solar system bodies
Solar System Research, 2014The morphometric parameters are examined for the shape of fragments of ordinary chondrites, iron meteorites, S- and C-class stony asteroids, metallic asteroids, and icy small bodies of the Solar System. All small Solar System bodies are shown to have, depending on their composition and, hence, physical and mechanical properties, a specific shape that ...

Mechanical evolution of small solar system bodies
2023This dissertation presents a series of studies that develop and apply numerical modeling techniques to small bodies in the solar system. We are particularly interested in low-energy deformations, collisions, and disruptions, and our subjectsrange from near-Earth asteroids to Kuiper belt contact binaries in the farthest reaches of the solar system.

Dynamic simulation of small solar system bodies
Astronomical & Astrophysical Transactions, 1998Abstract As part of a dynamical study of small transneptunian bodies, in particular, of the cometary Oort cloud, a simulation of orbital evolution under the influence of the Galactic gravitational field was performed. The tidal Galactic potential includes a term corresponding to the Sun's orbital motion around the Galaxy's centre (core) in the point ...

Migration of Small Bodies in the Solar System
Earth, Moon, and Planets, 1996We investigate several parts of the process of migration of small bodies to the Earth from the asteroid and transneptunian belts. The obtained characteristic times up to collisions of near-Earth objects with the Earth are less than those obtained by other scientists.

Lift-Off Velocity on Solar-System Small Bodies
Journal of Guidance, Control, and Dynamics, 2017The lift-off velocity is defined as the velocity at which a particle, moving tangentially on the surface of some arbitrary body, will lift off from that surface and enter orbit.
