The region has a large number of small bodies. These bodies are mostly made up of rock and ice. The trans-Neptunian region is sometimes called the "outer Solar System", though those words are used more often to describe the region beyond the [[asteroid belt]].

=== Kuiper belt ===
The [[Kuiper belt]] is made 
up of debris [[wikt:similar|similar]] toof [[wikt:scattered|scattered]] pieces of rock just like the asteroid belt. However, iIt is mostly made up of ice and can be found between 30 and 50 [[AU]] from the Sun. Inside the Kuiper belt are three [[dwarf planet]]s and [[Small solar system body|small Solar System bodies]]. Many of the largest Kuiper belt objects such as [[Quaoar]], [[Varuna]] and [[Orcus]], may be reclassified ascalled dwarf planets at some time. There are over 100,000 Kuiper belt objects with a diameter graterhich are more than 50 km across. The total mass of the Kuiper belt is thought to be only a tenth or even a hundredth of the mass of the Earth. Many Kuiper belt objects have multiple [[satellite]]s, and most have orbits that take them outside of the [[ecliptic]]ore than one moon.

The Kuiper belt can be roughly divided into the "[[Classical Kuiper belt object|classical]]" belt and the [[Resonant trans-Neptunian object|resonances]]. Resonances are orbits linked to that 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, after the first of their kind to be discovered, ((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.
