Many Brits will be heading out on a late night stroll this week as the UK sees its last supermoon of the year.
A full moon appears roughly once a month, every 29.5 days. However, there are only four or five supermoons throughout the year.
Between 2020 and 2025 there will only be four supermoons a year, and the last one of 2022 is in August and coming later this week.
So if you're a supermoon super-fan, or want to see one for the first time, make sure you're around for an early-hours walk on Friday August 12.
When is the supermoon this week?
The supermoon will be seen in the night sky in the early hours of the morning at 01:30am on Friday August 12 – the last supermoon of the year.
The moon will appear 14% bigger and up to 30% brighter as it lights up the dark sky on Friday morning.
What is a supermoon?
Supermoons occur when the full moon coincides with the point in its orbit closest to Earth. This makes the moon appear much bigger and brighter than a regular lunar sighting.
Even supermoons can vary – the biggest of the century is predicted to take place in December 2052.
When the moon is at its furthest point away from the Earth during an orbit, that is called a micromoon – with it appearing much smaller and dimmer too.
How long will the supermoon last?
Supermoons appear once a month over four months during a cycle, with this week's being the last one.
Sara Russell from the Natural History Museum said: "During a supermoon, the moon is at a stage where it is closest to Earth. This will typically last for two to five full moons, so that’s why there are multiple supermoons in a row.
"After that, the moon goes into the more distant part of its orbit."
Sara continued: "The moon, of course, does not vary in size according to where it appears in the sky."
When will the supermoon be next year?
As we approach the end of this supermoon cycle, the next one is not expected to start until August 2023. This marks the start of another four-month spell of supermoons.
So, if you're hoping to catch the last supermoon of the year, make sure you've got an alarm ready for 1:30am on Friday August 12, to enjoy the moon appearing bigger and brighter than normal.
Just watch out for the werewolves.
