Its surface is only 40 degrees above absolute zero, covered with exotic ice. We think it's going to be like kids in a candy store, arriving in a system like this.

And we had teams of scientists up on the surface, and it would ram its way up through (the ice). 17 times they went through the polar ice.

Just as a Chihuahua is still a dog, these ice dwarfs are still planetary bodies.

Pluto has strong atmospheric cycles: it snows on the surface; the snows sublimate and go back into the atmosphere each 248 year orbit.

Just as a Chihuahua is still a dog, these ice dwarfs are still planetary bodies. The misfit becomes the average. The Pluto-like objects are more typical in our solar system than the nearby planets we first knew.

I think when people see Pluto revealed by New Horizons, its satellite system, its complex surface, its atmosphere, I think they'll have a hard time saying 'That's not a planet' because it obviously will be, and I think most people are already coming to that opinion anyway, but I think that's really going to drive it home viscerally.
