NASA's Hubble Space Telescope has measured the
largest object in the solar system ever seen since the discovery of Pluto 72
years ago.
Approximately half the size of Pluto, the icy world 2002 LM60,
dubbed "Quaoar" (pronounced kwa-whar) by its discoverers, is the
farthest object in the solar system ever to be resolved by a telescope.
It was initially detected by a ground-based telescope, as simply a
dot of light, until astronomers aimed the powerful Hubble telescope at it.
Quaoar is about 4 billi
