Haumea family
As a member of the Haumea family, is suspected of being an icy mantle collisional fragment from dwarf planet Haumea. With an absolute magnitude (H) of 4.7, and a Haumea-family albedo of 0.7, this object would have a diameter of 158 km.

Observations by Mike Brown in 2012 using the W. M. Keck Observatory suggest that does not have a companion.
