It used to be said that Pluto is a misfit. But now we know Earth is the misfit. This is the most populous class… — Alan Stern Copy Share
The Kuiper belt region, which I call the third zone because it lies beyond the rocky terrestrial planets and beyond the giant planets, is… — Alan Stern Copy Share
I think if you were between maybe 6 and 16, there was nothing like Apollo, and I wonder if there can be something like… — Alan Stern Copy Share
If you put Earth out beyond Neptune, you wouldn't be able to call it a planet because it couldn't clear its zone. — Alan Stern Copy Share
When we first sent missions to Jupiter, no one expected to find moons that would have active volcanoes. And I could go down a… — Alan Stern Copy Share
Pluto is still active four and a half billion years into its history. It was expected that small planets like Pluto would cool off… — Alan Stern Copy Share

We're going to find Marses and maybe Earths out in the solar system's attic of the Oort Cloud and the Kuiper Belt. — Alan Stern Copy Share
One of the implications of the discovery of the Kuiper Belt and its many small planets is that many scientists now think of the… — Alan Stern Copy Share
CASIS has to succeed because for it not to succeed would be a huge setback for the International Space Station program. — Alan Stern Copy Share
