Pluto: The Frozen Planet

Pluto: The Frozen Planet

Explanation:
|
The Hubble Space Telescope imaged [ http://www.ast.cam.…] Pluto and its moon Charon in 1994. Pluto [ http://seds.lpl.ari…] is usually the most distant planet from the Sun [ http://antwrp.gsfc.…] but because of its elliptic orbit Pluto crossed inside of Neptune [ http://antwrp.gsfc.…]'s orbit in 1979 and will cross back out again in 1999. Compared to the other planets, very little is known about Pluto. Pluto [ http://www.c3.lanl.…] is smaller than any other planet and even smaller than several other planet's moons. From Pluto, the Sun is just a tiny point of light. Pluto [ http://dosxx.colora…] is probably composed of frozen rock and ice, much like Neptune's moon Triton [ http://antwrp.gsfc.…]. Pluto has not yet been visited by a spacecraft, but a mission [ http://www.jpl.nasa…] is being planned for the next decade. Tomorrow's picture: Our Solar System from Voyager
