context_page_description: 2013 FT₂₈ is a trans-Neptunian object. The existence of the TNO was discovered on 16 March 2013 at Cerro Tololo Observatory, La Serena and 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 may have some resonant interaction with the known giant planets.
  Its argument of perihelion is similar to that of another TNO, 2015 KG163.
