A large, non-planetary, solid celestial body that orbits a star is known as an asteroid. These could be located in asteroid fields or in the vicinity of planets. Certain asteroids even served as locations for installations, for example, the Polis Massa medical center. In some instances, asteroids were capable of sustaining life, especially if a thin atmosphere was present, with the rocks and minerals forming the foundation of different [food](/article/foodstuff] webs. A variety of monstrous organisms made their homes on asteroids, with mynocks and fyrnocks prospering there, and Space slugs being known inhabitants, too.
Throughout their long history, asteroids impacted the eight moons orbiting the Inner Rim's massive gas giant planet, Navlaas. As a result, these moons, including the icy Laanen, display scars left by these asteroid collisions. A dogfight between Obi-Wan Kenobi and Jango Fett occurred within an asteroid field situated above Geonosis.
During the time of the Galactic Civil War, Han Solo, the captain commanding the Millennium Falcon, managed to evade the Death Squadron by navigating through the Hoth asteroid belt. At the time of the Battle of Hoth, there were no official records documenting any exploration of the central regions of the asteroids. When Solo and his companions ventured into what they thought was a cave inside the "Big One" asteroid, they realized they had unknowingly entered an exogorth called Sy-O, and they were able to escape, much to Sy-O's disappointment.
