Asteroids are rocky cosmic objects smaller than planets. There are about 1.1 to 1.9 million asteroids in our solar system. One of them is Bennu. September 11, 1999 LINEAR (Lincoln Near Earth Asteroid Research) Bennu was discovered in the near-earth asteroid survey.

Asteroid Fragmentation and Evolution of Asteroids
Annual Review of Earth and Planetary Sciences, 2000To understand the complex collisional history of asteroids and explain their observed characteristics, it is necessary to be able to describe the fundamental physics of large-scale impact events. Because data collected on collisional outcomes is derived from small-scale laboratory experiments, success at describing asteroid evolution hinges ...

Itokawa is an S-type near-Earth asteroid, numbered 25143. This irregular object has been the first asteroidal target for a sample return mission: the JAXA Hayabusa-1 mission. It has established that Itokawa is very small (530 × 290 × 210 m) and has a density of about 1,900 kg/m−3, leading to a rather high porosity.

Icarus, 1995
Abstract Asteroid 2953 Vysheslavia, a Koronis family member about 15 km in diameter, very close to the outer edge of the 5/2 Kirkwood gap, has been shown by numerical integrations to fall into the resonance; then it approaches Jupiter and ends up into a hyperbolic orbit. The typical dynamical lifetime is of the order of 10 Myr.

LISA is a joint ESA–NASA mission aiming for cosmic gravitational wave detection and analysis. We address here the question of a special kind of signal caused by asteroid encounters. We present a short theory of the detection of such signals.

On the Stochasticity of the Asteroid Belt [PDF]
, 1998 The study of the stochasticity of the asteroid belt requires the analysis of a large number of orbits. We detect the dynamical character of a set of 5 400 asteroids using the Fast Lyapunov Indicator, a method of analysis closely related to the computation of the Lyapunov Characteristic Exponents, but cheaper in computational time.
