A satellite in low orbit typically about 800 km from the Earth is exposed to an immense gravitational pull and has to move at considerable speed in order to generate a corresponding centrifugal force. There is a direct connection between the distance from the Earth and the orbital velocity of the satellite. At a distance of 36,000 km, the orbiting time is 24 hours, corresponding to the Earth's rotation time. At this distance, a satellite above the Equator will be stationary in relation to the Earth.
Depends on the Altitude of the Satellite. Most are around 90 minutes. The closer an object is to the Earth, the faster it must circle to balance the gravitational pull of the Earth. The closest satellites (~100+ km) are in in low Earth orbit (LEO); these can circle the Earth in as little as 90-100 minutes. Any lower than this and the atmosphere would quickly slow the object down so that it would fall back to Earth after relatively few orbits.
