Feb 28, 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.
Wikimedia Commons has media related to Main Belt asteroids. 42 of the largest objects in the asteroid belt. If possible, asteroids should always be placed into one of the numerous sub-categories, in line with the category information given in the minor-planet catalog.
(main belt) The zone near to the plane of the ecliptic and between the orbits of Mars and Jupiter that contains the majority of asteroids, known as main-belt asteroids. The edges are well-defined at distances from the Sun of about 1.7 and 4.0 AU respectively and the orbits are strongly concentrated in the plane of the ecliptic.
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).
The asteroid belt region is also termed the main belt to distinguish it from other concentrations of minor planets within the Solar System, such as the Kuiper belt and scattered disc. (→Asteroid belt)
