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.
The Sun warms our planet, and with the Moon, creates the tides. The Moon orbits the Earth and in turn, the Earth orbits the Sun. We see the Universe from a platform that is both rotating on its axis, and traveling in an elliptical orbit around the Sun.ometimes the Moon is above this orbit and sometimes itâs below, so it doesnât block the light from the Sun, or get caught in the Earthâs shadow. The Sun and the Moon work together to create the tides we experience here on Earth.
