The Kuiper belt (/ ˈ k aɪ p ər / KY-pər) [1] is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. [2] It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive.
A classical Kuiper belt object, also called a cubewano (/ ˌ k juː b iː ˈ w ʌ n oʊ / "QB1-o"), [a] 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 ...
Over one thousand bodies were found in the Kuiper belt orbiting between about 30 and 50 AU from the Sun in the twenty years after finding 15760 Albion. This revealed a vast belt of bodies, more than just Pluto and Albion themselves. [17] [18] By 2018, over 2000 Kuiper belt objects were discovered. [18]
With a nearly circular orbit at around 40 to 50 AU, Varuna is classified as a classical Kuiper belt object (KBO). [3] Varuna's semi-major axis of 42.8 AU is similar to that of other large classical KBOs such as Quaoar (a=43.7 AU) [26] and Makemake (a=45.6 AU), [27] although other orbital characteristics such as inclination widely differ.

The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [16] [17] [18] An astronomical unit, or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [19]

Over one thousand bodies were found in a belt orbiting between about 30-50 AU from the Sun in the twenty years (1992-2012), after finding 1992 QB1 (named in 2018, 15760 Albion), showing a vast belt of bodies more than just Pluto and Albion. [9] [10] By 2018, over 2000 Kuiper belts objects were discovered. [10]
28978 Ixion (/ ɪ k ˈ s aɪ. ə n /, provisional designation 2001 KX 76) is a large trans-Neptunian object and a possible dwarf planet.It is located in the Kuiper belt, a region of icy objects orbiting beyond Neptune in the outer Solar System.
