Just as a Chihuahua is still a dog, these ice dwarfs are still planetary bodies.
I don't believe we should classify planetary objects by location. We should use properties of the objects as a guide.
Exploring Pluto and the Kuiper Belt is like conducting an archaeological dig into the history of the outer solar system, a place where we can peek into the ancient era of planetary formation.
I like to call this mission the Everest of planetary exploration. It's really fantastic.
Our result suggests other bodies in the Kuiper Belt may have more than one moon. It also means planetary scientists will have to take these new moons into account when modeling the formation of the Pluto system.
