Image above: These time-lapse images of a newfound planet
in our solar system, called 2003UB313, were taken on Oct. 21,
2003, using the Samuel Oschin Telescope at the Palomar
Observatory near San Diego, Calif. The planet, circled in white,
is seen moving across a field of stars. The three images were
taken about 90 minutes apart.
Scientists did not discover that the object in these pictures was
a planet until Jan. 8, 2005. Image credit: Samuel Oschin Telescope,

Image above: This artist's concept shows the planet catalogued
as 2003UB313 at the lonely outer fringes of our solar system. Our
Sun can be seen in the distance. The new planet, which is yet to
be formally named, is at least as big as Pluto and about three
times farther away from the Sun than Pluto. It is very cold and
dark. The planet was discovered by the Samuel Oschin Telescope
at the Palomar Observatory near San Diego, Calif., on Jan. 8, 2005.
