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 ...

They often describe scattered disc objects as "scattered Kuiper belt objects". [108] Eris, which is known to be more massive than Pluto, is often referred to as a KBO, but is technically an SDO. [107] A consensus among astronomers as to the precise definition of the Kuiper belt has yet to be reached, and this issue remains unresolved.
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 ...

This list contains a selection of objects 50 and 99 km in radius (100 km to 199 km in average diameter). The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following ...
