Abstract

Since1984 asteroid study is conducted at Department of Astronomy, Bandung Institute of Technology. At present there are two main streams in our research, dynamical and physical study. Astronomers determine the orbital elements of more than 12000 asteroids, and the number is increasing. In the distribution of orbital elements of asteroids, there are several features such as Kirkwood gap, groups, and families. To know the dynamical evolution of asteroids, it is very important to study these features. Recently some small bodies of our solar system have been approached to the Earth, one of them was Toutatis. These objects are interested to study. Based on 2384 asteroids taken from NASA.File the phenomenon of orbital elements a, e, i, {\Omega}, {\omega} and Tisserand invariant, T of Near-Earth asteroids are briefly described.
