The term perigee-syzygy or perigee full/new moon is preferred in the scientific community. Perigee is the point at which the Moon is closest in its orbit to the Earth, and syzygy is when the Earth, the Moon and the Sun are aligned, which happens at every full or new moon.
What is the meaning of perigee and apogee?
The moon’s distance from Earth varies throughout its monthly orbit because the moon’s orbit isn’t perfectly circular. Every month, the moon’s eccentric orbit carries it to apogee – its most distant point from Earth – and then, some two weeks later, to perigee – the moon’s closest point to Earth in its monthly orbit.

What does perigee Syzygy mean?
The Moon makes one full orbit around Earth in about 29.53 days, which means that it reaches its perigee and apogee points about once a month. When this occurs at the same time as a full moon, it’s called a perigee syzygy—or, more commonly, a supermoon!
Why do we always see the same face of the moon?
“The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every time it circles the Earth.

How often is syzygy?
Syzygy occurs when the Moon and Sun are aligned, an event that happens twice monthly. The effect on Earth is that the gravitational pull of these two space bodies is strengthened, increasing the elevation of high tides and decreasing low tides.
Why do Supermoons happen?
A supermoon occurs when the Moon’s orbit is closest (perigee) to Earth at the same time the Moon is full. … When a full moon appears at perigee it is slightly brighter and larger than a regular full moon – and that’s where we get a “supermoon.
