2012 VP₁₁₃, also known by its nickname "Biden", is a trans-Neptunian object of the sednoid population, located in the outermost reaches of the Solar System. It was first observed on 5 November 2012 by American astronomers Scott Sheppard and Chad Trujillo at the Cerro Tololo Inter-American Observatory in Chile.^[1]^[2] The discovery was announced on 26 March 2014.^[10]^[12] The object probably measures somewhere between 300 and 1000 km in diameter, possibly large enough to be a dwarf planet.
