Description: O Cinturão de Kuiper é uma faixa de pequenos objetos gelados no Sistema Solar exterior, localizados principalmente além da órbita de Netuno. A maioria desses objetos encontra-se a distâncias de 40 a 48 unidades astronômicas do Sol.

Os objetos no Cinturão de Kuiper são em sua maioria pequenos, embora vários planetas anões possam ser encontrados lá, incluindo Plutão. Ao contrário dos pequenos corpos e planetas anões no cinturão de asteroides, os objetos do Cinturão de Kuiper são compostos principalmente por água congelada, metano e amônia.
