What is a super moon?

A supermoon is a combination of two different astronomical effects.

It’s when a new or full moon coincides with a perigee — the moon’s closest point in its monthly orbit.

A moon must come within 90% of its closest approach to Earth to be officially defined as a supermoon.

This means that the moon must be within 224,865 miles of earth and must be a full moon on top of that.

How is a supermoon formed?

First you need a full moon when the moon is fully illuminated from Earth’s perspective.

For this, the earth must be between the sun and the moon.

This means that we see the moon’s entire face illuminated by the sun.

Although the Earth is between the Sun and the Moon, it does not produce an eclipse because the Moon’s position is slightly skewed relative to our home planet.
And for a supermoon, the moon must also be in the correct position in orbit around the earth.

The Moon has an elliptical orbit and is not always exactly the same distance from Earth.

Its closest point is called perigee, and its farthest point is apogee.

A full moon at perigee gives you a super moon.

And a full moon at apogee gives you a micro moon.

when is the next

Supermoons are relatively rare, occurring only three or four times in a year.

That’s because it requires a full moon in addition to a low-Earth orbital positioning.

There are only two super moons in 2022.

The first was on June 14th – that was the Super Strawberry Moon.

And the second is July 13th – the Super Buck Moon.

They should be very easy to see when you look up.

This is especially true for the supermoon on July 13th, which is the largest of the year.

Just pray it’s not a cloudy night…

That harvest moon appears around the time of the autumnal equinox when farmers tend to get their main harvest done.

A supermoon appears when it is closest to Earth and therefore brightest, with the next appearing in September.

A blood moon occurs during a total lunar eclipse, the next scheduled for May 2020.

Each month of the year actually has its own particular full moon phenomenon, they are as follows:
