(contracted; show full) be roughly divided into the "[[Classical Kuiper belt object|classical]]" belt and the [[resonant trans-Neptunian object]]s. Resonances are orbits linked to the orbit of Neptune. The first resonance begins within the orbit of Neptune itself. The classical belt consists of objects having no resonance with Neptune, and extends from roughly 39.4 AU to 47.7 AU. Members of the classical Kuiper belt are classified as cubewanos. They are called this because the first one of their kind to be discovered, 
[[(15760) 1992 QB1|(15760) 1992 QB<sub>1</sub>]], was called QB<sub>1</sub> for short. The orbits of cubewanos are still very circular.

=== Plutinos, Makemake and Haumea ===
The largest object in the Kuiper belt is [[Pluto]], which is 39 AU. It was discovered in 1930 and was considered to be the ninth planet. As a result of the 2006 definition of a planet, Pluto was described as a dwarf planet. Pluto's largest moon, [[Charon]], sometimes orbit each other. Beyond Charon, four smaller moons [[P5]], [[Nix]], [[P4]] and [[Hydra]] orbit arou(contracted; show full)

Eris (68 AU) is the largest known scattered disc object. There has been a debate on weather or not it should be described as a planet. This is because it is 25% more larger and about the same diameter of Pluto. It is the largest known dwarf planet in the Solar System. It has one moon, [[Dysnomia]]. Eris and Pluto have a similar orbit.
