The last time two full supermoons appeared in the same month was in 2018. It won't happen

again until 2037.

The second supermoon of the month, which also happens to be the closest and brightest full moon of 2023, will make its appearance on Wednesday night.

The moon will be closer than usual, a mere 222,043 miles away, on the night of Aug. 30, 2023, making it appear slightly brighter and bigger than normal, giving it the supermoon title.

But that's not the only special feature about this full moon. Because it’s the second full moon in the same month, it will also be what's called a blue moon.

The last time two full supermoons graced the sky in the same month was in 2018. It won’t happen again until 2037, according to Italian astronomer Gianluca Masi, founder of the Virtual Telescope Project.
