V774104 is a trans-Neptunian object (TNO) wi a radius rochly hauf that o Pluto or somewhit smawer. Currently it is approximately 103 AU frae the Sun,[5][6] a distance o 15.4 billion kilometres (9.6 billion miles).[7] As o the discovery annooncement in November 2015, it is the maist distant observed naitural object in the Solar Seestem.[6][8] Na astrometry haes been submittit tae the Minor Planet Center, sae thare are na publicly kent orbital elements.

Notes[eedit | eedit soorce]

  1. The size estimate o 500–1000 km leads tae an absolute magnitude (H) o 3.5–4.0, which at 103 AU is apparent magnitude 24–24.5.
