2. What is the density of Venus?

Answer: 5.2 that of water

Earth's density is 5.5 that of water, making Earth slightly more dense than Venus. Mercury fits in between Venus and Earth at 5.4 times the density of water.

3. The ancient Greeks thought Venus was two different planets, what did they call them?

Answer: Phosphorus and Hesperus

Answer: True

Yes it does. Here are two theories on why Venus rotates backwards. First, an object hit Venus so hard that it reversed the rotation of the planet.

This theory appeared in Sky and Telescope).
