The International Space Station travels in orbit around Earth at a speed of roughly 17,150 miles per hour (that's about 5 miles per second!). This means that the Space Station orbits Earth (and sees a sunrise) once every 92 minutes!
There are 24 hours in a day, therefore the ISS revolves around the Earth approximately 16 times per day. The number varies very slightly because it is based upon orbital altitude. When the ISS is closer to the Earth, it orbits more quickly and when the ISS is farther from the Earth, it orbits more slowly.
