The Moon’s orbit is elliptical; it is shaped like a flattened circle. Because of this shape, the distance between the Moon and the Earth is different at different positions and it varies as it moves around the Earth.
When the Moon is closest to the Earth on its orbit, it is said to be at perigee. The word perigee is of Greek origin and means ‘near Earth’. At perigee, the Moon is 356,400 kilometres away from the Earth.
The word apogee comes from a Greek word that means ‘far from Earth’. When the Moon is at the farthest point from Earth in its orbit, it is said to be at apogee. At apogee, the Moon is 406,700 kilometres away from the Earth.
