What is Pluto classified as in the solar system?

Pluto is considered to be two different things. 1. Pluto is a dwarf planet. It is in hydrostatic equilibrium (round) and it orbits the sun, but it has not cleared its neighborhood of debris. What's its neighborhood? The Kuiper belt, a collection of icy objects similar to comets that somewhat resembles the asteroid belt. This leads to its second classification. 2. Pluto is a Kuiper Belt Object (KBO). Specifically, it's classified as a plutino - an object within a certain zone of the Kuiper Belt.
