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).
Other articles where main-belt asteroid is discussed: asteroid: Distribution and Kirkwood gaps: …AU, a region called the main belt. The mean distances are not uniformly distributed but exhibit population depletions, or “gaps.” Those so-called Kirkwood gaps are due to mean-motion resonances with Jupiter’s orbital period. An asteroid with a mean distance from the Sun of 2.50 AU, for ...
Jan 1, 2014 · Once its eccentricity reaches a value of about 0.3, a main-belt asteroid's orbit begins to approach or even cross the orbit of Mars. Close encounters with Mars can further alter its orbit, leading to interactions with the other inner planets or with Jupiter, which eventually results in a collision with either a planet or the Sun, or ejection ...

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. Over the last years evidence has grown that planetesimals formed big from the gravitational collapse of a local ...
