(308933) 2006 SQ372 is a small trans-Neptunian object discovered through the Sloan Digital Sky Survey by Andrew Becker, Andrew Puckett, and Jeremy Kubica on images first taken on September 27, 2006 (with precovery images dated to September 13, 2005).<ref name="MPEC2007-A27"/><ref>An Icy Wanderer from the Oort Cloud</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=news }}</ref>

It has a strongly eccentric orbit, crossing that of Neptune near perihelion but bringing it more than 1,500 AU from the Sun at aphelion.<ref name="Buie"/> It takes about 22,500 years to orbit the barycenter of the Solar System.<ref name="Kaib2009"/> The large semi-major axis makes it similar to (87269) 2000 OO67 and 90377 Sedna.<ref name="Kaib2009"/> With an absolute magnitude (H) of 8.1,<ref name="jpldata"/> it is estimated to be about 60 to 140 km in diameter.<ref name="h"/> Michael Brown estimates that it has an albedo of 0.08 which would give a diameter of around 110 km.<ref name="Brown-dplist"/>

The object could possibly be a comet.<ref name="Kaib2009"/> The discoverers hypothesize that the object could come from the inner Oort cloud,<ref name="Kaib2009">{{#invoke:Citation/CS1|citation |CitationClass=journal }}</ref> but other scientists like California Institute of Technology's Michael Brown also consider other possibilities, as "it may have formed from debris just beyond Neptune [in the Kuiper belt] and been 'kicked' into its distant orbit by a planet like Neptune or Uranus".<ref>{{#invoke:citation/CS1|citation |CitationClass=news }}</ref>
