planetary system

(all the planets orbiting a star)

A planetary system consists of the non-stellar objects orbiting a star. Of current observational interest are planets and circumstellar disks, but such systems are presumed to have as much variety as the solar system in terms of smaller bodies.

The term stellar system has a similar meaning, but includes the star (or binary star).

A planetary system may involve planets orbiting more than one star, e.g., circumbinary planets.
