Well, geostationary satellites are satellites which moves around in the same manner as the earth. This is true. and the derivations indicates that the centripetal force are provided by gravitational force of the earth on the satellite which causes the circular motion. However, the Earth rotates from the West to the East. but the force doesn't imply the direction of circular motion(i.e. closewise/anti-closewise or the same manner as the earth/opposite to that). Hence, is it possible to move in the opposite direction as the Earth? the energy required seems not the same ? I can't see any deviations on the net. Thanks.
