What are Some Prominent Features of the Asteroid Belt?

The asteroid belt is a dense area of asteroids between the orbits of Mars and Jupiter in the solar system. It is calculated from 120,437 asteroids that have been numbered. 98.5% of the asteroids are found here.

In the early days of the formation of the solar system, due to collisions during the accretion process, small particles gradually gathered to form larger clusters. Once they gathered enough mass (so-called MSI), they could use gravity to attract surrounding matter. These planets can stably accumulate mass into rocky planets or huge

The asteroid belt has only a fraction of the mass of the original asteroid belt. Computer simulations show that the original mass of the asteroid belt may be comparable to that of Earth. However, due to gravity interference, most of the material was ejected during the formation cycle of millions of years, and the remaining mass was only about one thousandth of the original.

When the main belt started to form, a condensation line (snow line) below the water temperature had formed in the area 2.7AU away from the sun. Stars formed outside this line could accumulate ice. The main-belt comets generated in the asteroid belt are outside this line, thus becoming the main factor that causes the oceans of the earth.

Asteroids are still affected by many subsequent processes, such as internal heating, melting due to impact, and weathering from space bombarded by cosmic rays and micrometeoroids.

· The inner boundary of the main band has a 4: 1 orbital resonance (at 2.06 AU) with Jupiter's orbital period. Any celestial body will be ejected because of its unstable orbit.
