is a trans-Neptunian object approximately 220 kilometers (140 miles) in diameter. As of 2021 it is approximately 90 AU (13 billion km) from the Sun. At the time of its announcement in March 2018, it was the third most distant observed natural object in the Solar System, after Eris and 2014 UZ224. At a visual apparent magnitude of 26.2, it is one of the faintest trans-Neptunian objects observed and only the largest telescopes in the world can observe it. Being so far from the Sun, 2015 TH367 moves very slowly among the background stars and has only been observed eight times over 355 days. It requires an observation arc of several years to refine the uncertainties in the approximately 700-year orbital period and determine whether it is currently near or at aphelion (farthest distance from the Sun). As of 2021 the nominal JPL Horizons solution has it coming to aphelion around the year 2288, whereas Project Pluto (which only fit 5 of the 8 observations) shows it reached aphelion around 2015.

Sa découverte a été annoncée en mars 2018 comme étant l'un des objets transneptuniens avec la plus faible magnitude apparente jamais découvert. (fr) |
