(also written (87269) 2000 OO67) is a small trans-Neptunian object (TNO) discovered by Deep Ecliptic Survey in 2000. It is remarkable for its highly eccentric orbit. At aphelion it is over 1,000 AU from the Sun and, with a perihelion of 21 AU, almost crosses the orbit of Uranus at closest approach. Some astronomers list it as a centaur.〔〔(Structure and Dynamics of the Centaur Population: Constraints on the Origin of Short-Period Comets )〕 came to perihelion in April 2005.〔(【引用サイトリンク】url=http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=87269 )〕 Both and take longer than Sedna to orbit the Sun using either heliocentric coordinates or barycentric coordinates. == See also ==
