Asteroids are small planetary bodies revolving around the sun, located
between the orbits of Mars and Jupiter. Their obits around the Sun average
about 4.6 years. The largest eliptical orbit is Hidalgo (944), which has
an orbit of 13.71 years. The shortest is Icarus (1566), which has an orbit
of only 408 days. The only asteroid sometimes visable with the naked eye
is Vesta. The asteroids Ceres, Pallas, Juno and Vesta contain more than
half the total mass of the asteroid belt. There are about 20 Asteroids
larger than 100 miles in diameter. Ceres, the largest, is about 480 miles
(772 km.) in diameter. About 30,000 are known and some 1700 have been
studied.
The origin of the Asteroids is unknown. Some theories account for the
Asteroids via a catastrophic collision of small planets. The collisions
are believed to have occured as recently as a 100 million years ago. This
is supported by estimated ages of many Earth meteor craters.
