Cis-Neptunian object


A cis-Neptunian object is, literally, any astronomical body found within the orbit of Neptune.[1] However, the term is typically used for those distant minor planets other than trans-Neptunian objects: that is, all sub-planetary bodies orbiting the Sun at or within the distance of Neptune, but outside the orbit of Jupiter.[citation needed] This includes the icy minor planets known as centaurs[2] and the Neptune trojans.[3][a]
