Kurzfassung
Asteroids are rocky bodies orbiting the Sun with diameters of up to about 1000 km, most of which are found in the asteroid belt with semi-major axes from about 2 to 3.5 AU. In contrast to comets asteroids do not normally display comas or tails. As of December 2008 there were about 200000 numbered asteroids. The rate of discovery of asteroids increased dramatically in the 1990s with the availability of sophisticated CCD detectors and powerful computers. Telescope search programs can now cover large areas of sky in one night and scan large amounts of image data automatically for the presence of moving objects. The search programs are largely motivated by the hunt for near-Earth asteroids but the number of near-Earth detections is very small compared to the number of main-belt detections in the same period (around 1%).
