Suppose a satellite were placed in orbit around (and very close to)a neutron star.Which theory would you need to use to describe how it moves?

The intense gravitational field around a neutron star would require the use of the general theory of relativity to accurately describe the motion of the satellite. Kepler's laws and Newton's law of gravitation are not designed to handle such extreme gravitational environments. While the special theory of relativity deals with the effects of high speeds and velocities, it does not directly account for gravity.
