Explanation:
The fastest planet revolving around the sun is Mercury because it is the closest planet to the sun. However even if it is the closest planet to the sun, it's still not the hottest. Venus is the hottest planet because it has thicker atmosphere of mostly carbon dioxide (carbon dioxide is a greenhouse gas and it has the ability to trap heat). The planet that is most similar to Earth is Mars. After the Earth, Mars is the most habitable planet in our solar system. Gravity on Mars is 38% that of Earth, which is believed by many to be sufficient for the human body to adapt to. It has an atmosphere that offers protection from cosmic and the Sun's radiation. And the slowest planet to revolve around the sun is Neptune. It is because it is the farthest planet from the sun, it has an extremely wide orbit and a comparatively slow orbital velocity.
