Pluto
|
|
Pluto, too small and far away to be seen except through the
largest of telescopes.

The smallest planet in our solar system and also the farthest
away from us, remains basically a mystery. We know very little about Pluto. We
do know that on its surface there is methane ice or snow, and it has an
atmosphere of methane gas. No detail of its surface is visible from Earth but
the Hubble telescope revealed dark and light regions. It has one moon named
Charon. Pluto is less than one-fifth the size of Earth, even smaller than our
Moon. |
