Haumea family
As a member of the Haumea family, 2005 CB79 is suspected of being an icy mantle collisional fragment from the dwarf planet Haumea. With an absolute magnitude (H) of 4.7,[4] and a Haumea family albedo of 0.7, this object would have a diameter of 158 km.[7]
Observations by Mike Brown in 2012 using the W. M. Keck Observatory suggest that 2005 CB79 does not have a companion.[11]
