The ISS isn’t visible every night, and sightings will only be for a few minutes when it’s overhead. Sighting opportunities can range from several in a week to once a month, but there should be plenty of chances to spot the ISS before Christmas.
To help you work out when it’s visible over the festive period where you live – have a look at our guide on how to spot the International Space Station with top tips on when, where and how you can spot the ISS.
You can also use NASA’s online tool to find out when the ISS can be seen from wherever you are. They even offer a downloadable app.
Excitingly – if you don’t mind a very early start to Christmas Day – the ISS will be visible above the UK (weather permitting) at 05:56 for around 4 minutes or so.
