2011 GM27 is a trans-Neptunian object (TNO) in the Kuiper belt. It orbits slightly outside a 3:5 resonance with Neptune, taking 16 years (5.5% of its orbit) longer to orbit the Sun than a body in 3:5 resonance. It was discovered on 2 April 2011 at ESO's La Silla Observatory in Chile. With an absolute magnitude of 5.2,[2] it is probably a dwarf planet, as its diameter has been roughly estimated to be about 450 kilometers based on an assumed geometric albedo of 0.06.[3] It has a Tisserand's parameter relative to Jupiter of 5.771.[2] Precovery observations exist dating back to 2006 in SDSS data.[4]
