A Supermoon refers to a full moon that occurs when the moon is at its closest point to the Earth, called the perigee. It appears 14% larger and 30% brighter than a full moon at the farthest point from the Earth, called the apogee (Mini Moon).

The moon's phases change on a 29.5-day cycle, with about an 11-day difference each year. Because of this, every 2 years and 8 months, a full moon appears twice in one month. A Blue Moon refers to the second full moon occurring within a single month.

It is rare for a Supermoon and a Blue Moon to occur simultaneously. The most recent occurrence was on January 31, 2018. At that time, it was the first Super Blue Moon total lunar eclipse in 36 years since 1982. The Supermoon, which appears larger as the moon approaches Earth, the Blue Moon, which is the second full moon in a month, and the total lunar eclipse, where the entire moon is covered by Earth's shadow, all happened at the same time.

The next Super Blue Moon will be on January 31, 2037, 14 years later. This will also be a Super Blue Moon total lunar eclipse.
