Gravity in the Solar System. Newtonâs law of gravity allows the planets and other objects to take only certain types of orbit. These are circular, elliptical, parabolic or hyperbolic orbits. This list is in order of increasing energy for a given distance of closest approach to the Sun (perihelion). Both parabolic and hyperbolic orbits are open.
