Full Moon tonight: Friday the 13th brings a rare Micromoon

There are no concrete rules as to how far away the Moon must be to qualify as a Micromoon.

However, there are commonly accepted definitions used by most astronomers.

A micromoon is a Full Moon or New Moon taking place when the Moon’s centre is farther than 251,655 miles 405,000km from the centre of Earth.

Supermoon, meanwhile, is a Full or New Moon occurring when the Moon’s centre is less than 223,694 miles (360,000km) from the Earth’s centre.
