(provisional designation ) is a trans-Neptunian object that resides in the Kuiper belt. It has a 3:7 resonance with Neptune. It was discovered on April 8, 2002 by Marc W. Buie, Amy B. Jordan, and James L. Elliot. Assuming a generic TNO albedo of 0.09, it is about 153 km in diameter.
Simulations by Emel'yanenko and Kiseleva in 2007 show that has a 99% probability of libration in a 3:7 resonance with Neptune.
The Neptune 3:7 mean-motion resonance keeps it more than 11 AU from Neptune over a 14000-year period.
It has been observed 21 times over 4 oppositions and has an orbit quality code of 3.
