Planet

A planet is an astronomical object, often found in orbit of a star, or being orbited by moons. Planets could be terrestrial or a gas giant, and were found in star systems. Some planets did not have a star system, for one reason or another. Many planets were also inhabited with sentient life. A planet entirely covered with cities is known as an ecumenopolis.Star Wars
