It was discovered on July 26, 2003 by Michael E. Brown, Chad Trujillo and David L. Rabinowitz at Palomar Mountain in California. Origin{{Main|Haumea family}}Based on their common pattern of infrared water-ice absorption and the clustering of their orbital elements,[9] the other KBOs {{mp|1995 SM|55}}, {{mpl|(19308) 1996 TO|66}}, {{mpl|(55636) 2002 TX|300}} and {{mpl|(145453) 2005 RR|43}}, among others, appear to be collisional fragments broken off the dwarf planet {{dp|Haumea}}. The neutral color of the spectrum of these objects in the visible range evidences a lack of complex organics on the surface of these bodies that has been studied in detail for the surface of Haumea.[10] References1. ^List Of Transneptunian Objects {{webarchive |url=https://www.webcitation.org/5Pkgpyk4n?url=http://cfa-www.harvard.edu/iau/lists/TNOs.html |date=2007-06-21 }} 2. ^{{Cite web |title=MPEC 2009-R09 :Distant Minor Planets (2009 SEPT. 16.0 TT) |date=2009-09-04 |publisher=IAU Minor Planet Center |url=http://www.cfa.harvard.edu/mpec/K09/K09R09.html |accessdate=2009-10-04}} 3. ^{{Cite web |author=Marc W.
