But there's not one but two this month
Image via LadbibleGet your telescope ready as a 'Sturgeon' supermoon will be lighting up the sky this week.
On Tuesday 1st August, the second full supermoon of the year - the 'Sturgeon' supermoon - is set to occur at 19:31 before rising at 21:23 and will be visible - that's if it's not cloudy.
A supermoon is a full moon which appears larger in the sky, because it's closer to the Earth.
But if you miss out on seeing the supermoon on Tuesday - don't worry because there will be a second opportunity this month - on the on the 30th of August.
When there are two full moons in a month, the second appearance is called a "blue moon".
Ladbible report it usually takes the Moon about 29.5 days to complete a full cycle, meaning that most of the time there is only one full Moon in the month.
However, occasionally it happens that the full cycle falls within a month and we have two.
But, it's worth noting that Blue Moon is not actually blue in colour and is more likely to appear orange than blue.
