Newly discovered dwarf planet is solar system’s most distant object

12 November 2015 Astronomy Now

Designated V774104, the body is 500 to 1000 kilometres in diameter and is currently 15.4 billion kilometres, or 103 astronomical units (AU) from the Sun, but its exact orbit is yet to be determined.
