4.1 Introduction. The Moon revolves around Earth in an elliptical orbit with a mean eccentricity of 0.0549. Thus, the Moon's center-to-center distance from Earth varies with mean values of 363,396 km at perigee to 405,504 km at apogee.t illustrates the Moon's orbit around Earth and Earth's orbit around the Sun. The relative sizes and distances of the Sun, Moon, and Earth as well as the eccentricity of the Moon's orbit are all exaggerated for clarity. The major axis of the Moon's orbit marks the positions of perigee and apogee.
But wait a second and think. The Moon follows the Earth around the Sun in its orbit, and if you didnât have the Earth, the Moon would really be orbiting the Sun. So can we say that the Moon is really orbiting the Sun? No. But the case is pretty compelling. First, take a look at the orbital velocity of the Moon. The Moonâs velocity around the Moon is a mere 1 km/second. But the Moonâs velocity around the Sun is 30 km/sec; same as the Earth. And hereâs something stranger. the Moon doesnât follow a spiral pattern around the Sun, as you would think, but it always follows a convex path compared to the Sun.
