V774104

V774104 is a trans-Neptunian object (TNO) with a radius roughly half that of Pluto or somewhat smaller. Currently it is approximately 103 AU from the Sun, a distance of 15.4 billion kilometers (9.6 billion miles). As of the discovery announcement in November 2015, it is the most distant observed object in the Solar System. No astrometry has been submitted to the Minor Planet Center, so there are no publicly known orbital elements.

Discovery

V774104 was discovered by a team using the Subaru Telescope, a large reflecting telescope at the summit of Mauna Kea with a primary mirror 8 meters (26 ft) in diameter. The discovery was announced at the November 2015 meeting of the American Astronomical Society’s Division for Planetary Sciences; the discovery team was led by Scott Sheppard and Chad Trujillo.

Orbit

No astrometry has been released publicly so the object does not have a minor planet designation and the uncertainties of the orbital elements are unknown. Being a trans-Neptunian object so far from the Sun with an observation arc of just a few weeks at the time of its discovery announcement, its perihelion and aphelion have not been securely determined.
