(87269) 2000 OO67 (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.[1][4]
(87269) 2000 OO67 came to perihelion in April 2005.[1][3][5]
Both (87269) 2000 OO67 and 2006 SQ372 take longer than Sedna to orbit the Sun using either heliocentric coordinates or barycentric coordinates.
