How your kids can see Santa's sleigh in the sky for three minutes on Christmas Eve
If you’ve got Christmas-mad kids in the house, showing them Santa’s sleigh in the sky will leave you with some big smiles.
On Christmas Eve you can see Father Christmas and his cargo - also known as the International Space Station (ISS) - flying high above you.
It will only be visible for three minutes - and you’ll have to forgo a festive lie in, as it will become clear from 6.06am on December 24th.
Since it’s early, you’ll need to tell the little ones that Father Christmas is simply delivering presents to other parts of the world, and will drop by later.

For your best chances to spot it, try looking south-west in the sky.
It’s also a good idea to check the weather forecast since if it’s a cloudy day it won’t be visible.
However, there’ll be a second chance on Christmas Day morning - when you’ll need to tell the kids Santa is on his way home.
