Here's the breakdown:
* Apogee: The prefix "apo-" comes from the Greek word "apo", meaning "away from". Therefore, apogee means "the point farthest from the earth".
* Perigee: The prefix "peri-" comes from the Greek word "peri", meaning "around" or "near". Therefore, perigee means "the point closest to the earth".
Both words are used to describe the points in the orbit of an object around the Earth, like a satellite or the moon.
