A transneptunian object is any object in the Solar System whose orbit is located partially or totally beyond the orbit of the planet Neptune. Some specific subdivisions of that space are named Kuiper Belt, Scattered Disc and Oort Cloud. By a 2008 resolution of the International Astronomical Union, the Transneptunian dwarf planets were renamed plutoids. The abbreviation TNO is often used to refer to the transneptunian object.
