What is the typical orbital speed required for a Low Earth Orbit (LEO) satellite?

Answer

Around 27,000 kilometers per hour

Satellites operating in Low Earth Orbit (LEO), which are situated much closer to the planet, must achieve considerably higher speeds than higher-altitude counterparts to successfully counteract the stronger gravitational pull experienced at those lower ranges. The typical velocity cited for a LEO satellite is approximately 27,000 kilometers per hour, which translates to about 17,000 miles per hour. This incredible velocity is necessary to achieve the required centripetal acceleration needed to stay in orbit, yet this speed also causes them to traverse the visible sky very rapidly, appearing overhead for only a brief few minutes before disappearing below the horizon.
