Santa's Sleigh, of course, otherwise known as the International Space Station (ISS), which will be unmistakable as it flies across the skies this Christmas Eve and Christmas Day. Why you need to plan carefully to see itHowever, while it may be relatively easy to locate at a very precise time above your home this Christmas, the ISS will arrive at an inconvenient time in the early morning, before dawn on Christmas Eve and Christmas Day. Either way, it's best to know in advance so you can make a plan for such a precise event, though obviously, you will also need clear skies, something you cannot plan for. Where to See 'Santa's Sleigh' on Christmas Eve and Christmas DayThese are the lucky cities where 'Santa's Sleigh' will appear bright and relatively easy to see (in a clear sky) on Christmas Eve and/or Christmas Day. I've therefore only included details for the brightest, longest crossings overhead some of the world's biggest cities on Christmas Eve and Christmas Day.
