(contracted; show full)t was discovered in 1930 and was called the ninth planet. A new definition for the word ''planet'' was made in 2006. Because of this, Pluto is now called a ''dwarf planet''. Pluto has five moons. Pluto's largest moon, [[Charon]], orbits closest to Pluto. Beyond Charon, four smaller moons [[S/2012 P 1|S/2012 (134340) 1]], [[Nix (moon)|Nix]], [[S/2011 P 1|S/2011 (134340) 1]] and [[Hydra (moon)|Hydra]] orbit around Pluto. Pluto orbits the Sun twice for every three 
Neptunian orbitorbits of Neptune. Kuiper belt objects who orbits in this area are called "plutinos".

Makemake (45.79 AU) is smaller than Pluto. It is the largest object in the classical Kuiper belt. Makemake is the brightest object in the Kuiper belt after Pluto. In 2008, it was described as a dwarf planet. Haumea (43.13 AU) has a similar orbit of Makemake. However, it is caught in a 7:12 orbital resonance with Neptune. It is about the same size as Makemake and has two satellites. It has a fast 3.9-hour rotation, which makes it seem as though Humea is flat an(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.
