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][3] {{mp|(87269) 2000 OO|67}} came to perihelion in April 2005.[4][5][6]Both {{mp|(87269) 2000 OO|67}} and {{mpl|(308933) 2006 SQ|372}} take longer than Sedna to orbit the Sun using either heliocentric coordinates or barycentric coordinates.
