We had three in 2016, and the one on November 16 of that year was the closest we've had since 1948, according to NASA, and we won't have another one like that until 2034.
If you miss the moon on the first day, don't fret, the moon will still appear large and bright for a few days after that, it just won't be a full a moon.
According to Michelle Nichols, director of public observing at Chicago's Adler Planetarium, there is a reason behind the moon's captivating close approach to the Earth. The supermoon will rise on Sunday, 3 December and will become full at 3:47pm GMT - remaining bright and full throughout the night. On Dec. 3 Earth will view its only visible "supermoon" of the year, making the planet's moon appear much larger and brighter than at any other point in 2017.
This Sunday will make selenographists the world over very happy, as a bigger and brighter moon is set to be visible as it moves closer towards Earth.
The next full moon you're going to see will be absolutely extraordinary.

First and only Supermoon of 2017 is this weekend
Most astronomers suggest watching the supermoon right after sunset and into moonrise, and minutes before the next sunrise as well. The best time to watch a supermoon is when it's low, near the horizon. The moon will reach its perigee when it will be at a distance of 222,135 miles (357,492 kilometers) from earth on December 4 at 3:45 a.m. EST (0845 GMT, 2.15 IST). Due to an effect called the Moon Illusion, it may appear bigger.
"The moon's orbit is not a flawless circle".
Bill Ingalls, a NASA photographer, says that those capturing the event through their smartphones have to focus on the correct light balance.
To get an original shot, Ingalls suggests taking a picture that puts the moon in context of a local landmark, something that gives your photo a sense of place.
