Small (and Not So Small) Solar System Bodies
2010This chapter will cover the somewhat confusing terminology surrounding: How planets, dwarf planets, and asteroids are so defined. The meaning of the myriad of numbers and names used to designate asteroids. The quantities used to describe the orbit of an asteroid around the Sun – its orbital elements.

The Science of Small Solar System Bodies
2019On February 15, 2013, the city of Chelyabinsk, Russia was struck by a small rocky body about 20 m in diameter. The body exploded at a height of about 30 km above the ground. The resulting shockwave broke windows in over 7000 buildings and injured more than 1500 people.

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 ...

Phobos and other small bodies of the solar system
Planetary and Space Science, 1991Abstract Phobos is the first asteroid-like body to be observed at close range: during the Viking mission, several close fly-bys made possible extensive mapping of its surface at resolutions down to a few m. During the Phobos mission, two encounters at a distance of about 200 km were performed before the premature termination of the mission, on March ...

Water on Small Solar System Bodies
2011When examining the outer parts of the solar system water becomes more and more abundant. The water reservoir on the Erath and other terrestrial planets might have been supplied by the impact of these objects in the heavy bombardment phase of the early solar system evolution.

Populations of Small Solar System Bodies
2019Asteroids are objects that are mainly composed of rocky and metallic material, are generally accepted to be debris left over from the formation of the solar system. The exact composition varies with the asteroid, but in addition to rocky material, asteroids may contain metals and volatiles including organic material.

Space Weathering of Small Solar System Bodies
Earth, Moon, and Planets, 2009Micrometeorite bombardment and irradiation by solar wind and cosmic ions cause variations in the optical properties of the small Solar System bodies surface materials. These space weathering processes are reasonably well understood for the Moon and S-type asteroids.
