(provisional designation ) is a resonant and binary trans-Neptunian object, approximately 146km (91miles) in diameter, located in the outermost region of the Solar System. It was discovered on 27 March 2000, by astronomers John Kavelaars, Brett Gladman, Jean-Marc Petit and Matthew Holman at Mauna Kea Observatory on Hawaii. This distant object resides in an eccentric orbit and is locked in a 2:5 orbital resonance with Neptune. It is known to have a 111-kilometer sized companion, which was discovered in January 2007.

Orbit

has an extremely eccentric orbit which crosses the paths of many other trans-Neptunian objects, including almost all of the dwarf planets and dwarf planet candidates. As a result, its position alternates between the Kuiper belt and the scattered disc.

Resonance with Neptune

is part of a group of trans-Neptunian objects that orbit in a 2:5 resonance with Neptune. That means that for every five orbits that Neptune completes, makes only two. Several other objects are in the same orbital resonance, the largest of which is .

Satellite

Like many objects of the Kuiper belt and scattered disc, has a satellite. Provisionally designated S/2007 (60621) 1, the satellite was discovered by the Hubble Space Telescope seven years after itself was found. The moon orbits at 1180 kilometres away from, completing one orbit in approximately 7 days. It is thought to be 115 km in diameter, just 75.7% the diameter of 2000 FE8 itself.

Numbering

This minor planet was numbered by the Minor Planet Center on 14 June 2003., it has not been named.
