Asteroids, sometimes called planetoids, are large hunks of rock orbiting a sun, such as the one in Golarion's solar system. They are smaller than planets but larger than meteoroids. A large percentage of the solar system's asteroids can be found in the Diaspora. Some of these planetoids are as large as 600 miles across.
