2013 FT28 is a Trans-Neptunian object. The existence of the TNO was revealed on 30 August 2016. 2013 FT28 is the first high semi-major axis, high perihelion extreme trans-Neptunian object that is anti-aligned with the other known extreme trans-Neptunian objects such as Sedna and 2012 VP113 i.e. its longitude of perihelion differs by 180° from other objects. The orbit of 2013 FT28 appears stable though simulations showed that it there may be some resonant interaction the known giant planets.
