Can a planet orbit a moon (a binary planet system)?

The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them. Short Answer · Kinetic energy of the satellite K = 8.0 × 10 8 J · Gravitational force when the orbit radius is increased to 3 × 10 7 m is ( F 2 ) = 35.5 N ... ... planet orbiting the star.
