Here is a time-lapse sequence including two overhead passes by the International Space Station [ISS]. Both passes begin in the lower-left corner of the frame and end in the upper right.
The first pass occurs between 0:46 and 0:47, and the second pass between 1:05 and 1:07. The station appears as a streak of light in these 4-second exposures.

The ISS, whose first component, the Zarya module, was launched in 1998, now has approximately a dozen pressurized sections connected and orbiting about 250 miles [402 km] above the surface of the earth [drawing from NASA]:
