Asteroids

Asteroids are small rocky bodies that never came together in the early days of the solar system to form larger planets. Most asteroids lie in the enormous space between the orbits of Mars and Jupiter, an area called the asteroid belt.
Ceres, the largest of these asteroids and the first to be discovered, is almost 500 miles wide. Most asteroids, however, are much smaller.
In 1992, an asteroid called Toutatis passed close to Earth and astronomer Steve Ostro was able to bounce radar signals off it. From the reflection on the radar, he was able to discover that Toutatis actually looked like two asteroids close together.
