(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, crosses the orbit of Neptune at closest approach. 2000 OO67 is probably composed of rock and ices. Some astronomers list it as a centaur. [1]

2000 OO67 came to perihelion in April 2005.[1][2][3]
