Answer 2

The perihelion is the point in the orbit of a planet, asteroid or comet that is nearest to the sun. It is the opposite of aphelion, which is the point farthest from the sun. The word perihelion stems from the Greek words "peri," meaning near, and "Helios," meaning the Greek god of the sun.
