The Moon, presenting an elliptical orbit around the Earth, passes through two prominent points. The closest point to Earth in that orbit is called the perigee. At that point the Moon is slightly larger than when it is at apogee, the farthest point in its orbit from Earth.

What happens at perigee?

When the Moon is at perigee, the lunar tides are greater because the distance from Earth is less and therefore the gravitational pull is greater. In the same way, solar tides are also stronger when the Earth is closer to the Sun.

When is peak?

Apogee: Maximum distance at which a celestial object is in its translation around the Earth. Perigee: Minimum distance at which a celestial object is found in its translation around the Earth.

Where is the perigee of the Earth?

Apogee (from the Greek ἀπό ‘apart, far from’ and γεω- ‘terrestrial, relative to the planet Earth’) is the point in an elliptical orbit around the Earth at which a body is furthest from the center of the Earth. The opposite orbital point, the closest one, is called the perigee.

How long is perigee?


This time is approximately 27.3 days. The moon moves in an elliptical orbit in which the earth is one of its focuses and the distance between the earth and the moon varies regularly. When the moon is closest to the earth it is known as lunar perigee, and when it is furthest away it is known as lunar apogee.

What happens when the Moon is closest to Earth?

When the Moon’s orbit is at its closest point to the Earth we call it perigee and it is the moment in which we can observe that the Moon looks brighter and larger than normal. It coincides with the full moon and gives rise to what we know as a supermoon.

When is the apogee of the Moon?

The apogee is the opposite orbital point, that is, when the moon is at the farthest point of its orbit from the earth. Then we perceive it “smaller”. The Apogee does not necessarily coincide with any lunar phase.

Why is the Moon so close?

What we perceive as a larger moon is not real, but an optical illusion. Emmert’s law, size-distance invariance, which states that the relationship between perceived linear size and perceived distance is a simple function of visual angle.
