Plutino
- a nu se confunda cu Plutoid
Plutino este un obiect cosmic care are orbita în rezonanța 3:2 cu planeta Neptun, asta înseamnă că în timp ce Neptun se rotește de 3 ori în jurul Soarelui, obiectele denumite Plutino fac două asemenea rotații (comportându-se la fel ca planeta Pluton); orbitele acestor obiecte se intersectează cu cea a lui Neptun (la fel ca și orbita lui Pluton).[1]
