2014 FE72 is a trans-Neptunian object first observed on 26 March 2014, at Cerro Tololo Inter-American Observatory in La Serena, Chile. It is a possible dwarf planet,[5] a member of the scattered disc, whose orbit extends into the inner Oort cloud.[1] Discovered by Scott Sheppard and Chad Trujillo, the object's existence was revealed on 29 August 2016.[1][8] Both the orbital period and aphelion distance of this object are well constrained.[2] 2014 FE72 had the largest barycentric aphelion until 2018. However, the heliocentric aphelion of 2014 FE72 is second among trans-Neptunian objects (after the damocloid 2017 MB7). As of 2023, it is about 66 AU (9.9 billion km) from the Sun.[7]
