QUOTES BY Alan Stern

There was a time when Pluto - which NASA's New Horizons spacecraft at last explored in 2015, a mission I led - was considered the last planet. We now know there are thousands of other - possibly inhabited - planets.

People know a planet when they see one, and I think that's a pretty darn good test, in fact, for planethood.

I just think it's patently absurd for scientists to categorize objects on the basis of the numbers of objects that they can remember.

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.

As a planetary scientist, I don't know what else to call Pluto: It's big and round and thousands of miles wide.

If you put Earth out beyond Neptune, you wouldn't be able to call it a planet because it couldn't clear its zone.

How can an adjective in front of a noun not describe the noun? There are dwarf stars, but they're still considered stars.

Going to the Kuiper Belt is like an archaeological dig into the history of the solar system.

The big lesson of planetary science is when you do a first reconnaissance of a new kind of object, you should expect the unexpected.

It says something very deep about humans and our society, something very good about us, that we've invested our time and treasure in building a machine that can fly across three billion miles of space to explore the Pluto system.
