Which of the following statements best describes a planetary system?
A planetary system is made of a central star with several planets and other objects orbiting around it. The planets are bound to their orbits by gravity. Our solar system is an example of a planetary system. There are other planetary systems in the universe.
A planetary system has an inner and outer star that balances the gravitational waves.
