The number of times the ISS (International Space Station) orbits the Earth each day - or once every 90 minutes. That's a lot of sunsets and sunrises! Sunsets to view are getting few...goodnight Earth pic.twitter.com/FQpIbDbdD3.
That picture is just a single orbit. It takes the ISS about 90 minutes to fly once around the Earth. During that 90 minutes, the Earth has rotated about 22.5 degrees, so if it flew over a city in one orbit, that city won't be there for the next orbit.
