Detailed explanation-1: -It maintains an orbit with an average altitude of 400 kilometres (250 mi) by means of reboost manoeuvres using the engines of the Zvezda Service Module or visiting spacecraft. The ISS circles the Earth in roughly 93 minutes, completing 15.5 orbits per day.
Detailed explanation-2: -The ISS orbital altitude drops gradually over time due to the Earth’s gravitational pull and atmospheric drag. Periodic reboosts adjust the ISS orbit. As the ISS orbital altitude decays, the orbit tracks on Earth change slightly.
Detailed explanation-3: -The International Space Station (ISS) is a multi-nation laboratory, orbiting 248 miles (400 kilometers) above our heads. It perhaps comes as no surprise that the ISS can easily be seen and tracked from Earth.
