This view of Pluto was taken by the Hubble telescope. It shows Pluto with its slightly smaller moon Charon. Pluto is over 6 billion km from the sun, and has not yet been visited by a spacecraft. Its temperature is -240° C due to its great distance from the sun. Its highly irregular orbit makes it likely that Pluto was once an asteroid-like body that was perturbed out of its original orbit. (In fact, in 2006 Pluto was declared officially not a planet). It's orbit is so uncircular that for every 20 years out of its 249 year orbit, it isn't the furthest planet, but is closer than Neptune! In February, 1999, it moved out far enough from the sun to again be the furthest, and will remain so for the next 229 years. Find out more here.
