2004 PR107, also written as 2004 PR107, is an asteroid in the asteroid belt with an absolute magnitude (H) of 17.8.[2] It was discovered on August 11, 2004 by Cerro Tololo Inter-American Observatory,[1] and then lost due to a lack of follow-up observations.

With an observation arc of only 1 day (consisting of only 2 images), it was thought to be a trans-Neptunian object with a semi-major axis (a) of 46 AU.[1] Mike Brown's website listed it as a likely a dwarf planet with an estimated diameter of 555 km.[3] The lost asteroid was rediscovered as 2012 SQ31 and determined to be a small ~1 km asteroid in the asteroid belt.[2]
