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).
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 ...
The Simple English Wiktionary has a definition for: asteroid belt. 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.
A classical Kuiper belt object, also called a cubewano (/ ˌ k juː b iː ˈ w ʌ n oʊ / "QB1-o"), is a low-eccentricity Kuiper belt object (KBO) that orbits beyond Neptune and is not controlled by an orbital resonance with Neptune. Cubewanos have orbits with semi-major axes in the 40–50 AU range and, unlike Pluto, do not cross Neptune's orbit.
The Kirkwood gaps are visible in the main belt. A Kirkwood gap is a gap or dip in the distribution of the semi-major axes (or equivalently of the orbital periods) of the orbits of main-belt asteroids. They correspond to the locations of orbital resonances with Jupiter .
Jan 18, 2008 · The main belt region is shown in red, and contains 93.4% of all the objects. For reference, Mars orbits out to 1.666 AU, and Jupiter between 4.95 and 5.46 AU. The diagram was created by Piotr Deuar [1] using orbit data for 120437 numbered minor planets from the Minor Planet Center orbit database, dated 8 Feb 2006.

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.
