A California astronomer has discovered what he believes is the 10th
planet in our solar system, a group of NASA-funded researchers said
on July 29, 2005. The new planet, known as 2003UB313, has been
identified as the most distant object ever detected orbiting the
sun, California Institute of Technology astronomer Michael Brown
said. This artist's concept shows planet 2003UB313 at the lonely
outer fringes of our solar system. Our sun can be seen in the
distance. (Nasa/Reuters)
