(87269) 2000 OO67 (provisional designation 2000 OO67) is a trans-Neptunian object, approximately 64 kilometers (40 miles) in diameter, on a highly eccentric orbit in the outermost region of the Solar System. It was discovered by astronomers at the Chilean Cerro Tololo Inter-American Observatory on 29 July 2000.
Description
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. Astronomers with the Deep Ecliptic Survey classify it as a centaur rather than a trans-Neptunian object.[2][5] 2000 OO67 came to perihelion in April 2005.[2][1][6] Both 2000 OO67 and 2006 SQ372 are calculated to take longer than Sedna to orbit the Sun using either heliocentric coordinates or barycentric coordinates.
