2010 RF₄₃ is a trans-Neptunian object of the scattered disc orbiting in the outermost regions of the Solar System, approximately 600 kilometers in diameter. With an absolute magnitude of 3.7, it was fist observed on 9 September 2010, by astronomers at the La Silla Observatory in northern Chile.^[3]^[1] ^[4] Astronomer Mike Brown lists it as highly likely a dwarf planet.^[6]
