Pluto
=====

Pluto once was a planet but as of August 24, 2006 it is now considered a dwarf planet 
in the kupid belt. It is 3,675 million miles from the sun. The diameter of Pluto 
is 1,429 miles. The average surface temperature is -369 degrees F. The length of a 
year on Pluto is 1,429 earth days. Pluto has 0 rings and 3 known satellites- moons. 
When first discovered, it was thought that Pluto had only one moon but since then 
(in 2005) two more moons have been 'discovered'. If earth's mass = 1, then Pluto's 
mass is 0.002. Also assuming that earth's gravity = 1, Pluto's gravity is about 
equal to 0.07.
