What is a Supermoon?
A supermoon is a full moon or a new moon that nearly coincides with perigee—the closest that the Moon comes to the Earth in its elliptic orbit—resulting in a slightly larger-than-usual apparent size of the Moon as viewed from Earth. The technical name is a perigee-syzygy or a full Moon around perigee.
The Moon’s orbit around Earth is not a perfect circle, but rather an ellipse. This means that the Moon’s distance from Earth varies throughout its orbit. The Moon’s closest point to Earth is called perigee, and its farthest point is called apogee.
When a full moon occurs at perigee, the Moon appears slightly larger and brighter than usual. This is because the Moon’s apparent size is inversely proportional to its distance from Earth. So, when the Moon is closer, it appears larger.
Supermoons occur about once every 14 months. However, the term “supermoon” is not officially recognized by astronomers. It was coined by astrologer Richard Nolle in 1979.
The next supermoon will occur on August 30-31, 2023. It will be a blue moon, which means it will be the second full moon in a calendar month. This will be the first time a blue moon has coincided with a supermoon since 2012.

Super Blue Moon Is Coming
Super Blue Moon is coming up on August 30-31, 2023. It is a rare combination of three lunar events: a full moon, a blue moon, and a supermoon.
- A full moon occurs when the Moon is on the opposite side of the Earth from the Sun, and the entire face of the Moon is illuminated.
- A blue moon is the second full moon in a calendar month. This happens about once every 2.7 years.
- A supermoon occurs when the Moon is at its closest point to Earth in its orbit, called perigee. This makes the Moon appear slightly larger and brighter than usual.
The combination of these three events will make the Super Blue Moon the biggest and brightest full moon of the year. It will be visible to all of Earth, from North America to Europe to Asia.
The Super Blue Moon will not actually appear blue. The term “blue moon” is a misnomer that dates back to the 16th century. Originally, it referred to the third full moon in a season that has four full moons. However, the term has since come to mean any second full moon in a month.
The Super Blue Moon is a rare event, but it is not the only one that will occur in 2023. There will also be a total lunar eclipse on May 16, 2023, and a partial solar eclipse on October 25, 2023.

Here are some additional things to know about the Super Blue Moon:
- It will be the closest full moon to Earth since January 2018.
- It will be about 14% larger and 30% brighter than a typical full moon.
- It will rise in the east at sunset and set in the west at sunrise.
- The best time to view it will be around midnight when it will be highest in the sky.
