Apogee refers to the point in an orbit where an object is farthest from the body it is orbiting. For example, when a satellite orbits the Earth, its apogee is the highest point in that orbit. This concept is important in fields like astronomy and space exploration, as it helps scientists understand the dynamics of orbits. In contrast, the term "perigee" describes the closest point in the orbit to the Earth. Both apogee and perigee are crucial for calculating the orbits of various celestial bodies, including the Moon, artificial satellites, and spacecraft. Understanding these terms aids in mission planning and satellite deployment.
