The term `supermoon` refers to a full or a new moon rising near or while the moon reaches perigee, its closest distance to Earth in its orbit around the planet. This Blue Moon is also a supermoon, meaning it coincides with perigee, the point in the moon`s orbit when it`s closest to Earth. During a supermoon, the moon looks slightly brighter and around 14% larger than when it`s farthest from Earth. The `blue` in blue moon doesn`t refer to color but it`s frequency or rarity. It`s used to describe a second full moon in a calendar month, which typically have only one full moon. Around 25% of all full moons are supermoons, but only 3% of full moons are blue moons, according to NASA. The next super blue moon after this 2023 one will not be seen until January 2037.
