INSIDE THE ASTEROID BELT.

The asteroid belt, a ring of debris orbiting the Sun, was once thought to have the potential to form a planet, but this idea was debunked by the presence of Jupiter. The belt consists of millions of asteroids, but many are small particles, and its overall mass is only four percent that of the Moon. The largest object in the belt is Ceres, classified as a dwarf planet. Computer simulations suggest that the belt originally had a mass similar to Earth's, but Jupiter's gravitational pull prevented the fragments from fusing together. Jupiter's influence also caused gaps in the belt and may have thrown much of its mass outwards. The composition of asteroids varies, with some being carbon-based, others silicate-based, and others metal-based. The spaces between large objects in the belt are large enough for spacecraft to pass through safely. Collisions between asteroids can form asteroid families, and the largest asteroids have enough gravity to be spherical. Dust is produced through asteroid collisions and slowly spirals towards the Sun. Notable asteroids in the belt include Ceres, Sylvia, 1950 DA, 3200 Phaethon, 2005 YU55, 2008 TC3, and 2013 TV135.
