It came to perihelion around 1858.[2] It is currently 83.8 AU from the Sun[6] and moving away from the Sun at 1.04 kilometers per second (2,300 miles per hour).[7] The only large objects currently farther from the Sun are Eris (96.1 AU),[8] 2014 UZ224 (90.9 AU), 2015 TH367 (~89 AU), Gonggong (88.0 AU),[9] Sedna (85.1 AU),[10] 2013 FS28 (84.8 AU), and 2014 FC69 (84.7 AU). Because it is so far from the Sun, it only has an apparent magnitude of 23.6.[6]
