It was discovered on 16 March 2013 at Cerro Tololo Observatory, La Serena and announced on 30 August 2016.https://www.bbc.co.uk/news/science-environment-37223076 New Solar System objects revealed 2017-02-19 30 August 2016 bbcnews 2013 FT 28 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 VP 113, i.e. its longitude of perihelion differs by 180° from other objects. The orbit of 2013 FT 28 appears stable though simulations showed that it may have some resonant interaction with the known giant planets.Sheppard Scott S.
