(60621) 2000 FE₈ (provisional designation 2000 FE₈) is a resonant and binary trans-Neptunian object, approximately 146 kilometers (91 miles) 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.^[3]

Orbit[edit]

2000 FE₈ 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.^[1]

Resonance with Neptune[edit]

2000 FE₈ is part of a group of trans-Neptunian objects that orbit in a 2:5 resonance with Neptune.^[6] That means that for every five orbits that Neptune completes, 2000 FE₈ makes only two.^[3] Several other objects are in the same orbital resonance, the largest of which is (84522) 2002 TC302.

Satellite[edit]

Like many objects of the Kuiper belt and scattered disc, 2000 FE₈ has a satellite. Provisionally designated S/2007 (60621) 1, the satellite was discovered by the Hubble Space Telescope seven years after 2000 FE₈ itself was found.^[7] The moon orbits at 1180 kilometres away from 2000 FE₈, completing one orbit in approximately 7 days.^[4] It is thought to be 115 km^[4] in diameter, just 75.7% the diameter of 2000 FE₈ itself.

Numbering[edit]

This minor planet was numbered by the Minor Planet Center on 14 June 2003.^[8] As of 2021^[update], it has not been named.^[2]
