is a large member of the Kuiper belt
with an absolute magnitude
of 4. An absolute magnitude 4 means the diameter of the object is between 400 and 950 km, so it is very likely a dwarf planet
. It was discovered on 12 December 2004 at Palomar Observatory
.
It is currently at 35.8 AU from the Sun, near the perihelion.
Kuiper belt
The Kuiper belt , sometimes called the Edgeworth–Kuiper belt, is a region of the Solar System beyond the planets extending from the orbit of Neptune to approximately 50 AU from the Sun. It is similar to the asteroid belt, although it is far larger—20 times as wide and 20 to 200 times as massive...

Absolute magnitude
Absolute magnitude is the measure of a celestial object's intrinsic brightness. it is also the apparent magnitude a star would have if it were 32.6 light years away from Earth...

Dwarf planet
A dwarf planet, as defined by the International Astronomical Union , is a celestial body orbiting the Sun that is massive enough to be spherical as a result of its own gravity but has not cleared its neighboring region of planetesimals and is not a satellite...
