TAUSEEF MUSTAFA—AFP/Getty Images by [Mahita Gajanan](https://time.com/author/mahita-gajanan/) ## Mahita Gajanan Gajanan is an editor at TIME. Jan 30, 2018 8:36 PM UTC Sky watchers will see the moon looking brighter and larger on January 31 when three lunar events — including a supermoon — coincide for the first time in 35 years. But what exactly is a supermoon? A supermoon is a [full moon](http://time.com/5082027/wolf-moon-supermoon-january-2017/) at its closest point to Earth during its orbit, according to [Space.com](https://www.space.com/39208-super-blue-blood-moon-guide.html). While the [supermoon](http://time.com/5082027/wolf-moon-supermoon-january-2017/) will look larger and give off more light on January 31 than a regular full moon, the difference can be hard to spot with the naked eye. But the upcoming supermoon will be extra special because it is also a blue moon — the second full moon in a calendar month — and a blood moon, a moon which occurs during a lunar eclipse. A lunar eclipse happens when the Earth moves between the sun and the moon, blocking sunlight from hitting the moon. As this happens, the moon takes on a reddish color, which is how it got the name “blood moon,” according to Space.com. Because the January 31 supermoon is occurring during a lunar eclipse, and is also a blue moon and a blood moon, it is being called a “[super blue blood moon](https://www.space.com/39208-super-blue-blood-moon-guide.html).” The upcoming supermoon is the third of 2018 and will complete the “supermoon trilogy,” according to NASA. The last two supermoons occurred on January 1 and December 3. ## Transcript [ MUSIC ] ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/5125152/what-is-a-supermoon-january-2018/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/5125152/what-is-a-supermoon-january-2018/"},"headline":"What Is a Supermoon?
