International Space Station

.
The International Space Station orbits the Earth about 16 times each day. It takes the International Space Station (ISS) about 90 minutes to orbit the earth, meaning that it makes the journey around the planet about 16 times each day. As of July 2012, the ISS had traveled more than 1.75 billion miles (2.8 billion km). The voyage from Earth to the ISS takes about two days, partly because of the time that it takes to inspect a space shuttle prior to letting it dock onto the ISS.
