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.</p><p>A joint effort between JPL and the California Institute of Technology, the Palomar Observatory near San Diego houses a collection of famous telescopes, including the Hale 200-inch and Samuel Oschin 48-inch telescopes. The Palomar Adaptive Optics System, built by JPL and Caltech, corrects for the atmospheric blur of astronomical targets caused by turbulence in Earth's atmosphere. This system's camera was built by Cornell University, Ithaca, N.Y.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA08003" onclick="window.open(this.href); return false;" title="Voir l'image 	 PIA08003:  Newest Member of Our Solar System (Artist's Concept)	  sur le site de la NASA">Voir l'image 	 PIA08003:  Newest Member of Our Solar System (Artist's Concept)	  sur le site de la NASA.</a></div> |  | PIA08003:  Newest Member of Our Solar System (Artist's Concept)
