Tour of the Planets

Planetary Composition

On which planets could you LAND a spaceship?

{"title":"bottom","description":"You could enter the atmosphere of these planets, but you couldn't land. They lack a solid surface.

Correct.

Please try again.

Most Dense?

Which Planet is the Densest?

{"title":"jupiter","description":"This planet is not very dense. It is primarily made of gases, like very thick clouds. Clouds aren't very dense compared to rocks. Try again.

The density of the entire Earth is greater than what we see when we analyze surface rock. This leads us to believe that it must have a center of something VERY dense, like iron.
