This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System. The asteroid belt is the smallest and innermost known circumstellar disc in the Solar System.
Feb 28, 2019 · The Main Belt: A Gateway to the Formation and Early Evolution of the Solar System | Planetary News. Workshop, Sardinia, Italy | June 4-7, 2019. The Main Asteroid Belt is at the boundary of the inner and outer solar system. It marks a transition region from the rocky volatile-poor inner terrestrial planets to the outer gaseous and icy giant planets.

Location of the main belt This plot shows the location of the main belt with respect to the planets and the Sun as well as the orbital structure of asteroid inclinations and number density of objects (yellow represents the highest number density, blue the lowest). Figure from DeMeo and Carry (2014).
Cite. Summary. From the viewpoint of planet formation in the Solar System, Main Belt asteroids are the remnants of the so-called planetesimal population, the building bricks of planets that formed ubiquitously all over the Solar Nebula.
The asteroid belt or main belt is a ring of small and large rocks and dust between the orbits of Mars and Jupiter. The biggest object in the asteroid belt is Ceres, a dwarf planet. The Kirkwood gaps separate the asteroid belt into several groups.
An asteroid with a mean distance from the Sun of 2.50 AU, for example, makes three circuits…. Within the main belt are groups of asteroids that cluster with respect to certain mean orbital elements (semimajor axis, eccentricity, and inclination).
