What is a Black Supermoon?

According to the Old Farmer’s Almanac, some people call the second Moon in a single month a Black Moon.

This is the most common definition, which applies to the Full Moon occurring tonight.

Confusingly, Black Moon is also used where no New Moon occurs in a month.

This takes place approximately every 19 years in the year’s shortest month February.

This particular moon on July 31 is called a Black Supermoon because it will be close to its closest point to Earth, known as the perigee.

A Black Moon also describes the third New Moon in a season of four New Moons.

Each season usually sees three New Moons, but a fourth can occur, approximately 33 months apart.

During a New Moon, Earth’s natural satellite and the Sun have the same elliptical longitude, meaning the Moon is not visible from Earth.

As the moon cannot be seen, the surrounding stars appear more prominent in the night sky.

NASA Moon facts:

The Moon orbits Earth in an ellipse, an oval bringing the natural satellite closer to and farther from Earth as it travels.

The farthest point in this lunar ellipse is the apogee and is about 253,000 miles (405,500km) from Earth on average.

The Moon’s closest point is the perigee, which is an average distance of about 226,000 miles (363,300km) from Earth.

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.
