A tiny solar system is discovered in a far corner of our Galaxy. In that solar system the mass of the star is 300,000,000 kg and the mass of it's closest orbiting planet is 47,500 kg. If that planet is 23,400,000 meters away from the star, what is the force of gravity between that star and it's planet?
