orbital inclination
Sign in to saveAlso known as inclination
angle between a reference plane and the plane of an orbit
Orbital inclination is the angle between a reference plane (like Earth's equator or the plane of the solar system) and the actual path an object takes as it orbits. It matters because it determines things like which parts of Earth a satellite can observe, how much fuel is needed to reach an orbit, and whether objects in space might collide with each other.
