Other objects, such as 28978 Ixion (discovered in 2001) and 20000 Varuna (discovered in 2000) measure roughly 500 km across. [1] This has led gradually to the acceptance of Pluto as the largest member of the Kuiper belt. [citation needed] The brightest known dwarf planets and other KBOs (with absolute magnitudes < 4.0) are:
This is a list of trans-Neptunian objects (TNOs), which are minor planets in the Solar System that orbit the Sun at a greater distance on average than Neptune, that is, their orbit has a semi-major axis greater than 30.1 astronomical units (AU). The Kuiper belt, scattered disk, and Oort cloud are three conventional divisions of this volume of ...
While many asteroids are composed primarily of rock and metal, most Kuiper belt objects are composed largely of frozen volatiles (termed "ices"), such as methane, ammonia, and water. The Kuiper belt is home to most of the objects that astronomers generally accept as dwarf planets: Orcus, Pluto, [5] Haumea, [6] Quaoar, and Makemake. [7]
Ceres, 2.8 AU in the asteroid belt; Orcus 39.4 AU, Trans-Neptunian-Kuiper belt object; Pluto 39 AU, Kuiper belt (a planet until 2006) Haumea 43 AU, Kuiper belt; Makemake 45.8 AU, Kuiper belt; Eris 95.6 AU, Kuiper belt; Gonggong Scattered disc object, 34 to 101 AU; Quaoar Kuiper belt object, 41.9 to 45.4 AU; Sedna 76 to 506 AU
All asteroids should be sorted using a 0-padded 6-digit sortkey based on their numerical designation.Otherwise, their provisional designation should be used. For example:

The Kuiper belt is a relatively thick torus (or "doughnut") of space, extending from about 30 to 50 AU [18] comprising two main populations of Kuiper belt objects (KBOs): the classical Kuiper-belt objects (or "cubewanos"), which lie in orbits untouched by Neptune, and the resonant Kuiper-belt objects, those which Neptune has locked into a ...
Euler diagram showing the types of bodies orbiting the Sun. The following is a list of Solar System objects by orbit, ordered by increasing distance from the Sun.Most named objects in this list have a diameter of 500 km or more.
