V774104 is the internal designation for the trans-Neptunian object designated 2015 TH367, but in November 2015 press releases confused it with 541132 Leleākūhonua, which was provisionally designated 2015 TG387 and internally designated V302126.[1] as both objects were mentioned at the American Astronomical Society’s Division for Planetary Sciences meeting. Various news articles speculated that V774104 was currently 103 AU (15.4 billion km) from the Sun, but its observation arc was too short to know whether its perihelion (closest approach to the Sun) was even outside Neptune's influence.[2]
