1. The three characteristics that the inner plants have in common are that they are small, dense, and rocky. They are called terrestrial planets.

2. Three differences between Venus and Earth are that Venus's sun rises in the west, sets in the east, and it has retrograde rotation instead of what Earth has, which is prograde rotation. They are similar because they are about the same size, mass, and density.

3. Though Mercury is closest to the sun, Venus has a higher surface temperature. This is because Venus has a dense atmosphere, and it is very active. It has the greenhouse effect, which makes the temperature so high.
