The International Space Station is the largest man-made object in the sky, weighing in at around 100,000 pounds (the equivalent of more than 320 cars) and measuring 357 feet end-to-end.
Because it reflects light from the sun, it can look like a giant star - or, perhaps, a sleigh - as it passes by.
It has become quite common for parents to persuade small children that it is Santa Claus in his sleigh delivering presents on Christmas Eve.
A Virtual Astronomer has worked out that this year the ISS will pass over the UK in the late afternoon, rising in the west at 4.42pm*, passing low in the sky and setting in the south east at 4.50pm.
When the ISS passes over it will appear as an incredibly bright star like object or plane without flashing lights moving across the sky, it can be at times the brightest object in the night sky second to the Moon.
As the station rises (from a westerly direction) it usually gets brighter but can be a challenge to spot at first. Make sure you have checked where it will rise from.
So, Captain FTFer, your mission, should you choose to accept it, is to find this cache before the ISS. Then look over the road to watch it rise, pass over Sutton and then set somewhere over Eyeworth.
