What if a satellite went around the Earth in the opposite direction?

The animation shows retrograde and prograde rotation of celestial objects in Space.

The Earth is known to spin in the counter-clockwise direction when viewed from the top. It is known to spin at 1670 Km/hr which is extremely fast considering the size of the planet. From Earth, satellites are traditionally sent to space to rotate in the direction of the earth's rotation. This is normally done because of the speed advantage that the Earth provides to the satellite adding 1670 Km/hr to the speed of the satellites rotation this is known as a prograde orbit. Rotation in the opposite direction is known as retrograde orbits.
