Animation of the Moon's orbit around Earth, with the phase seen at upper left. The concentric rings mark out 100, 000-kilometre increments from Earth. The Moon's orbit is elliptical rather than circular, and its distance from Earth varies from around 362, 600 kilometres at its closest (perigee, open circle at bottom) to some 405, 400 kilometres at its furthest (apogee, closed circle at top). The Moon takes just less than 28 days to complete one orbit. The phase of the Moon depends on the angle between the Sun, Earth and Moon, as seen. The Sun is out of frame at the bottom in this animation. | |
