Weather satellites above Earth stay in perfect, geosynchronized orbit, so you can probably guess at which one is keeping an eye out for events like Sandy. New Yorkers? Probably GOES-13. Calfornians? Good ol’ GOES-15.

The satellites are 22,300 miles up, which puts them higher than most satellites, but that number’s key: any higher or lower and they’d move faster or slower than the Earth spins, putting them out of their carefully crafted orbit.
