1. perihelion

   Perihelion refers to the point in the orbit of a planet, asteroid, or comet where it is closest to the sun. It is derived from the Greek words 'peri', meaning near, and 'helios', meaning sun. The opposite of perihelion is aphelion, which is the point in an object's orbit when it is farthest from the sun.

Examples of Perihelion in a Sentence

1. Patrick Martin:

We'll first have to see what the status of the spacecraft is after perihelion and how well it is performing close to the comet, and later we will have to try and determine where on the surface we can have a touchdown.

2. Nicky Fox:
