| Comet Pojmanski |
The perihelion is the point in the orbit of a planet, asteroid or comet where it is nearest to the sun.
The word perihelion stems from the Greek words "peri," meaning near, and "helios," meaning the Greek god of the sun. (The similar word, perigee, refers to the nearest point in some object's orbit of earth.)
