Artificial satellites are rarely placed in retrograde orbit. This is partly due to the extra velocity required to go against the direction of the rotation of the earth.

So, the required speed for rotating without falling, for a geostatic and one moving at the opposite direction of a geostatic, is not the same and equal to u=√(GM/r)?
For Polar Orbits it's u=√(GM/r)?
