These entities are divided into "C," "S," and "X" groups depending on their spectral shapes in the SMASS and Tholen classification systems. One of these objects was discovered using the Titius-Bode Law and was located in a region where they typically are not found, (*) Kirkwood Gaps. Divided into Aten, Apollo, and Amor types, the ones beyond Neptune are collectively known as the Kuiper Belt, while examples of these include Vesta and Ceres. For 10 points, name astronomical objects present between Mars and Jupiter in a namesake "belt."
