(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]^[2]

2000 OO₆₇ came to perihelion in April 2005.^[1]^[3]^[4]

Both 2000 OO₆₇ and 2006 SQ₃₇₂ take longer than Sedna to orbit the Sun using either heliocentric coordinates or barycentric coordinates.
