2014 FE72 is a trans-Neptunian object and possible dwarf planet, a member of the scattered disc, whose orbit extends into the inner Oort cloud. Discovered by Scott Sheppard and Chad Trujillo, the object's existence was revealed on 29 August 2016.
Orbit
Its elongated orbit (eccentricity = 0.98) has a perihelion of 36.3 AU, an aphelion of ~3000 AU and an orbital period of ~58,000 years. The latter values are the largest known for any Solar System body that is not a long-period comet. It takes roughly 5 times longer than Sedna to orbit the Sun. The epoch of October 2021 will be when 2014 FE72 will have its smallest heliocentric aphelion of 2456 AU.
2014 FE72 last passed through perihelion around late 1965. In 2017, it will move from 61.5 AU to 62.2 AU from the Sun. It comes to opposition at the end of March.
