How are satellites kept in orbit
Web6 de mai. de 2013 · 01:30. So in the same 6 minutes it would take to free fall 640 km (400 miles), the ISS moves 8000 km (5000 miles) horizontally. Those two motions occur simultaneously, and the result is a smooth circular orbit. At higher altitudes gravity is weaker, and less horizontal speed is required to maintain orbit.
