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. mp|2000 OO|67 is probably composed of rock and ices. Some astronomers list it as a centaur. [ [http://www.springerlink.com/content/k6n4251846112n17/ Structure and Dynamics of the Centaur Population: Constraints on the Origin of Short-Period Comets] ]

2000 OO67 came to perihelion in April 2005. cite web |last = Yeomans |first = Donald K. |url=http://ssd.jpl.nasa.gov/horizons.cgi?find_body=1&body_group=sb&sstr=2000OO67 |title=Horizons Online Ephemeris System |publisher=California Institute of Technology, Jet Propulsion Laboratory |accessdate=2008-01-25] cite web
