Question

Is angular momentum constant for a satellite in orbit?

Answer 1

Answer:

Because the force of Newtonian gravity is a central force, there is no torque on a satellite orbiting a planet: the force is always parallel to the position vector. Therefore, angular momentum is conserved always in Newtonian gravitation, provided there are no externally acting forces.
