Asteroids(minor planets)

Post  mobil on Thu Jan 27, 2011 11:10 pm

Asteroids, sometimes called minor planets or planetoids, are bodies—primarily of the inner Solar System—that are smaller than planets but larger than meteoroids, with the exception of comets. The distinction between asteroids and comets is made on visual appearance when discovered: Comets show a perceptible coma (a fuzzy "atmosphere"), while asteroids do not.
