(provisional designation ) is a twotino, that is, a planetoid in a 1:2 orbital resonance with Neptune. It was discovered on November 16, 2002 at the Palomar Observatory. If its derived diameter is correct it would have a higher density than Pluto, which is unusual as it appears to be much smaller than the expected size at which a Kuiper belt object usually becomes solid.
Knowing how many twotinos there are may reveal whether Neptune took roughly 1 million or 10 million years to migrate about 7 AU from its birth location.
A natural satellite was reported to be orbiting (named S/2007 (119979) 1) on February 27, 2007. It is estimated to be from the primary, with an orbital period of days, an eccentricity of and an inclination of . Assuming similar albedos, it is a quarter the diameter of its primary, or around 81km (50miles) in diameter.
