I know this is the meme thread, but still:
Like many other satellites, the International Space Station is occasionally bright enough in the night sky to be seen by the naked eye. It is in one of the lowest orbits possible, about 242 miles overhead. ... A number of Web sites will tell you when the ISS will pass over your location--www.heavens-above.com is one.
EDIT: You see the light reflected off it. You do not see the fakernauts waving at you.
