Astronomers have found a dwarf planet three times farther away from the Sun than Pluto, making it the most distant known object in the solar system. 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.
