(87269) 2000 OO67 (provisional designation 2000 OO67) is a trans-Neptunian object, approximately 64 kilometers (40 miles) in diameter, on a highly eccentric orbit in the outermost region of the Solar System. It was discovered by astronomers at the Chilean Cerro Tololo Inter-American Observatory on 29 July 2000.

Description

edit

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. Astronomers with the Deep Ecliptic Survey classify it as a centaur rather than a trans-Neptunian object.[2][5] 2000 OO67 came to perihelion in April 2005.[2][1][6] Both 2000 OO67 and 2006 SQ372 are calculated to take longer than Sedna to orbit the Sun using either heliocentric coordinates or barycentric coordinates.

Comparison

edit
 
The orbits of Sedna, 2012 VP113, Leleākūhonua, and other very distant objects along with the predicted orbit of Planet Nine. The three sednoids (pink) along with the red-colored extreme trans-Neptunian object (eTNO) orbits are suspected to be aligned with the hypothetical Planet Nine while the blue-colored eTNO orbits are anti-aligned. The highly elongated orbits colored brown include centaurs and damocloids with large aphelion distances over 200 AU.
