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 may have some resonant interaction with the known giant planets.
