(308193) 2005 CB79 is a trans-Neptunian object that is a member of the Haumea family.[8]
As a member of the Haumea family, (308193) 2005 CB79 is suspected of being an icy mantle collisional fragment from 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.[6]
The + marks 2005 RR43 (B-V=0.77, V-R=0.41) on this color plot of TNOs. All the other Haumea-family members (2005 CB79: 0.73, 0.37) are located to the lower left of this point.
Observations by Mike Brown in 2012 using the W. M. Keck Observatory suggest that (308193) 2005 CB79 does not have a companion.[10]
