A Quote by Alan Stern

Of course Pluto is a planet: It's massive enough to have its shape controlled by gravity rather than material strength, which is the hallmark of planethood. — © Alan Stern
Of course Pluto is a planet: It's massive enough to have its shape controlled by gravity rather than material strength, which is the hallmark of planethood.
We really just didn't realize the diversity of planetary types in our solar system. Pluto looked like a misfit because it was the only one we saw. And just as a Chihuahua is still a dog, these ice dwarfs are still planetary bodies. They're large enough to make themselves round by self gravity, and they surely pass the test of planethood.
The planets. Now footnote, I'm including Pluto in the planets, because I think it's terrible what they did to Pluto. And it's still a planet to me. I grew up with Pluto as a planet, it will always be a planet.
Pluto is still active four and a half billion years into its history. It was expected that small planets like Pluto would cool off long ago and not still be showing geological activity. Pluto is, in fact, showing numerous examples of geological activity on a massive scale across the planet.
Why can't Pluto be a planet? Some people like Pluto. And if it doesn't exist then they don't have a favorite planet. Right? Please write back but not in cursive because I can't read cursive.
All Plutophiles are based in America. If you go to other countries, they have much less of an attachment to either the existence or preservation of Pluto as a planet. Once you investigate that, you find out that Disney's dog Pluto was sketched the same year the cosmic object was discovered. And Pluto was discovered by an American.
Compassion is not a dirty word. Compassion is not a sign of weakness. In my view, compassion in politics and in public policy is in fact a hallmark of great strength. It is a hallmark of a society which has about it a decency which speaks for itself.
I knew Pluto was popular among elementary schoolkids, but I had no idea they would mobilize into a 'Save Pluto' campaign. I now have a drawer full of hate letters from hundreds of elementary schoolchildren (with supportive cover letters from their science teachers) pleading with me to reverse my stance on Pluto. The file includes a photograph of the entire third grade of a school posing on their front steps and holding up a banner proclaiming, 'Dr. Tyson - Pluto is a Planet!'
People know a planet when they see one, and I think that's a pretty darn good test, in fact, for planethood.
I think if I had to choose, I would rather have gravity instead of zero gravity. It's fun for a while, but I'd rather live on Earth.
I work to promote the idea of sustainable capitalism driven by long-term considerations rather than quarterly profits, which seeks to better people's lives and the planet rather than destroy them.
The soul is the form of the body, but not as the shape of a statue is formatio et terminatio materiae, for form does not exist apart from material. There is no whiteness without a white object. But the soul is not a form in this simple sense, and in particular, is not the shape of the material it informs. Therefore, the shape of a being does not affect the being's soul, for then something lower would inform something higher, which is impossible.
Gravity is not controlled physically in us by one of the 5 ordinary senses. We always reduce a gravity experience to an autocognizance, real or imagined, registered inside us in the region of the stomach.
We are living as if we had three planets' worth of resources to live with rather than just one. We need to cut by about two-thirds our ecological footprint. For that we need one planet farming as well as one planet living - one planet farming which minimises the impact on the environment of food production and consumption, and which maximises its contribution to renewal of the natural environment
Genuine mental health would involve a balanced interplay of both modes of experience, a way of life in which one's identification with the ego is playful and tentative rather than absolute and mandatory, while the concern with material possessions is pragmatic rather than obsessive.
I am convinced that the deepest desire within each of us is to be liberated from the controlling influences of our own psychic madness or patterns of fear. All other things—the disdain of ordinary life, the need to control others rather than be controlled, the craving for material goods as a means of security and protection against the winds of chaos—are external props that serve as substitutes for the real battle, which is the one waged within the individual soul.
Pluto is not a planet, but I am.
