Putting a satellite into orbit

[QUOTE="Physgeek64, post: 5460872, member: 525932"] Well I would suppose that it is the minimum energy since this is when the effective potential its minimum, and is the only orbit that has no component to its radial velocity, whereas every other orbit (which already has a greater ##U_e##) would also gain more energy due to this radial component. Alternatively you can differentiate the orbital equation with respect to r, set the derivative to zero and find that the centripetal force is equal to the gravitational force, and can hence infer circular motion :) Im not sure- the question wasn't very clear. My problem was that orbits are always closed, so it can't be elliptical since this would cause the projectile to crash back into Earth from its original position. The only other possibility I could think of would be to have a circular orbit in which the projectile is essentially orbiting just above the surface of the moon? Thank you :) [/QUOTE]
