The+Most+Mind+Bogglingly+Complex+Place4

VENUS Okay try being the hottest planet in our solar system if thats not complicated enough, then try wrap your mind round this one. Venus is the hottest planet in the solar system with the downside that only about 2% of the sunlight actually makes it to the surface of the planet.

__**  Pluto  **__    Pluto is a very complex place. Just the atmosphere is complex enough to make a person crazy. The atmosphere is lost when within Neptune's orbit, and then comes back. And get this, on the night side the atmosphere is expected to freeze and come down in snowflakes.
