is a large
trans-Neptunian object (TNO) orbiting the
Sun near the outer edge of the
Kuiper belt
The Kuiper belt () is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. It is similar to the asteroid belt, but is far larger—20 times ...
. Its discovery images were taken in 2007, and its
absolute magnitude of 4.5 is one of the twenty brightest exhibited by TNOs. Assuming it has a typical
albedo, this would make it roughly the same size as
Ixion (about 530–620 km diameter).
In a paper in the Astrophysical Journal Letters András Pál and colleagues estimate a diameter for of .
Observations by Brown in 2012, using the
W. M. Keck Observatory, suggest that does not have a
companion.
, it is about 41.3
AU from the Sun.
