    2014 FE72 is a trans-Neptunian object[2] and possible dwarf planet,[3] 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][5]

    Orbit

    Its elongated orbit (eccentricity = 0.98) has a perihelion of 36.3 AU, an aphelion of ~4,000 AU and an orbital period of ~90,000 years.[2] The latter values are about 4 times and 8 times, respectively, those of Sedna, and the largest known for any Solar System body that is not a long-period comet. However, given the short observation arc and extreme eccentricity, these values are also poorly determined.[2]

    2014 FE72 last passed through perihelion around late 1965; as of 29 August 2016, it was 61.4 AU from the Sun.[2]
