What was foun in a belt between mars and Jupiter?

Answer 1

In between the planets Mars and Jupiter is a feature called the Asteroid Belt, which is a large area of asteroids, or space rocks. Some of these asteroids are hundreds of miles in diameter, and some are just boulder-sized. Some have regular orbits like the planets, others have orbits that are highly eccentric and actually cross the orbits of other planets like Earth, which means that collisions are possible. Dozens of these asteroids have actually been captured by the planets Jupiter and Saturn and are now natural satellites of those planets. Other asteroids are gravitationally "nudged" by planets occassionally during their trek around the sun. There are several theories about their existence, including them being the remnant of a failed planet that tried to form during the earliest part of our Solar System's history. Asteroids have been portrayed inaccurately in media; if you could travel through the Asteroid Belt, you would likely never even see one. Despite the large number of asteroids, the space they occupy is vast, and they are widely scattered.
