Quizplus · Accepted Answer

The International Space Station orbits at an average altitude of 360 km above the Earth's surface to stay above most of the Earth's atmosphere. This allows for clearer observations and experiments to be conducted without interference from atmospheric disturbances. The ISS is still affected by Earth's gravity at this altitude, but its orbital speed allows it to maintain a stable orbit.
