Quick Summary

In astronomy, apogee refers to the point in an object's orbit around Earth that is farthest from the planet's center. It is one of the two points in an elliptical orbit that are closest to and farthest from the center of attraction, known as the line of apsides. The opposite point to apogee is perigee, which is the closest point in the orbit to Earth.12

The term "apogee" can also be used more generally to describe the highest or farthest point of anything, such as the culmination of a civilization. For celestial bodies orbiting the Sun, the farthest point is called aphelion, and for those orbiting other stars, it's apastron.132
