Solar System belts are asteroid and comet belts that orbit the Sun in the Solar System in interplanetary space. [1] [2] The Solar System belts' size and placement are mostly a result of the Solar System having four giant planets: Jupiter, Saturn, Uranus and Neptune far from the sun. The giant planets must be in the correct place, not too close ...
The total mass of the asteroid belt is significantly less than Pluto's, and roughly twice that of Pluto's moon Charon. The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars.
Over 200 asteroids are known to be larger than 100 km, [45] and a survey in the infrared wavelengths has shown that the asteroid belt has between 700,000 and 1.7 million asteroids with a diameter of 1 km or more. [46] The absolute magnitudes of most of the known asteroids are between 11 and 19, with the median at about 16. [47]
The Quadrantids originate from asteroid 2003 EH1, unlike most meteor showers, which originate from comets, according to NASA. Asteroid 2003 EH1 takes about 5.52 years to orbit the Sun and could be ...
This list includes few examples since there are about 589 asteroids in the asteroid belt with a measured radius between 20 and 49 km. [176] Many thousands of objects of this size range have yet to be discovered in the trans-Neptunian region.
The Kuiper belt is a great ring of debris similar to the asteroid belt, but consisting mainly of objects composed primarily of ice. [195] It extends between 30 and 50 AU from the Sun. It is composed mainly of small Solar System bodies, although the largest few are probably large enough to be dwarf planets. [ 196 ]

2006 VW 139 is a non-family asteroid of the main-belt's background population. [9] It is both a binary asteroid and a main-belt comet, also known as "active asteroid".It orbits the Sun in the outer main-belt at a distance of 2.4–3.7 AU once every 5 years and 4 months (1,944 days; semi-major axis of 3.05 AU).
