If you think Santa isn't real, think again, because on Christmas Eve you'll be able to spot his sleigh for yourself.
And if that's not enough to convince you, we don't know what will.

OK, so we're not being totally truthful: the 'sleigh' is in fact the International Space Station (ISS) which revolves around Earth 16 times a day.
It's actually often visible if you know where to look, but this Christmas it's perfect for convincing the kids it's Santa on his way to do the rounds.
It will be visible for just a short window this year, so you need to be quick. You'll have three minutes to spot it on 24th December (06.01am) and 25th December (05.15am), and you're looking for a flash of light. Read on to find out how...

It's early doors so you'll need to tell the little ones he's just starting his rounds in other parts of the world.
Nasa explains that you can "watch the International Space Station pass overhead from several thousand worldwide locations.
"It is the third brightest object in the sky and easy to spot if you know when to look up."
They add: "Visible to the naked eye, it looks like a fast-moving plane only much higher and traveling thousands of miles an hour faster!"

For the best chance of spotting it, look south-west in the sky and remember you only have a three-minute window - so you need to be up bright and early.
Plus, the sky needs to be clear, so if it's a cloudy rainy day it's probably not worth getting out of bed.
If you missed it this morning, there's a second chance for you and your family to spot it on Christmas Day - just explain he's on his way home to the kids.
