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] Observations by Mike Brown in 2012 using the W. M. Keck Observatory suggest that {{mp|(308193) 2005 CB|79}} does not have a companion.[10] References1. ^{{Cite web |date=September 1, 2007 |title=MPEC 2007-R02 : 2003 UY413, 2003 UZ413, 2004 NT33, 2005 CA79, 2005 CB79, 2005 UQ513 |first=Brian G. |last=Marsden |work=IAU Minor Planet Center |publisher=Harvard-Smithsonian Center for Astrophysics |url=http://www.cfa.harvard.edu/mpec/K07/K07R02.html |accessdate=January 10, 2010}} 2. ^{{Cite web |title=MPEC 2010-A05 :Distant Minor Planets (14 January 2010.0 TT) |date=January 2, 2010 |publisher=IAU Minor Planet Center |url=http://www.cfa.harvard.edu/mpec/K10/K10A05.html |accessdate=January 10, 2010 |archiveurl=https://web.archive.org/web/20100114044305/http://www.cfa.harvard.edu/mpec/K10/K10A05.html |archivedate=14 January 2010 |deadurl=no |df= }} 3. ^{{Cite web |author=Marc W.
