System

"System" is a term that is flung around willy-nilly in the Star Wars Hexalogy[1]. It is never quite clear from its usage in the movies what is meant by the term, and the hosts and guests have often speculated back and forth on the meaning. However, it is an actual term used in astronomy. It refers to any group of bodies in space that orbit around each other. The Solar system consists of our sun, Sol, and all the planets, planetoids, asteroids, and comets that orbit it. The Earth and its moon (Luna) can also be thought of a system. This was discussed in ROTJ Minute 105
