orbital eccentricity
Sign in to saveAlso known as eccentricity
parameter that determines the amount by which an orbit deviates from a perfect circle
Orbital eccentricity is a number that measures how much an object's orbit around another object differs from a perfect circle. It matters because it helps us understand and predict the paths of planets, moons, and other objects moving through space.
