Apogee (astronomy)

In astronomy, apogee is the point in an object’s orbit around Earth where it is farthest from the planet. During its journey, a satellite or the Moon repeatedly moves closer and farther from Earth. The apogee marks the maximum distance, while the opposite point is called perigee, which is the closest approach. These distances are important for understanding orbital dynamics and adjusting satellite operations. Apogee helps astronomers and engineers plan for communication, navigation, and observation tasks by knowing when satellites are at their greatest distance from Earth.
