A Quote by Neil deGrasse Tyson
Pluto's orbit is so elongated that it crosses the orbit of another planet. Now that's... you've got no business doing that if you want to call yourself a planet. Come on, now! There's something especially transgressive about that.

Most Jupiter-sized planets orbit the mother star in a highly elliptical orbit. This means they will often cross the orbit of any Earth-like planet and fling it into outer space, making life impossible. But our Jupiter travels in a near-perfect circular orbit, preventing a collision with any Earth-like planet, making life possible.
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.
Phil Taylor's got the consistency of a planet ... and he's in a darts orbit!
When the space shuttle's engines cut off, and you're finally in space, in orbit, weightless... I remember unstrapping from my seat, floating over to the window, and that's when I got my first view of Earth. Just a spectacular view, and a chance to see our planet as a planet.
If the Earth is the size of a pea in New York, then the Sun is a beachball 50m away, Pluto is 4km away, and the next nearest star is in Tokyo. Now shrink Pluto's orbit into a coffee cup; then our Milky Way Galaxy fills North America.
The dead spacecraft in orbit have become a permanent fixture around our planet, not unlike the rings of Saturn. They will be the longest-lasting artifacts of human civilization, quietly circling the Earth until the sun turns into a red giant about 5 billion years from now.

I can't honestly account for the very personal response that I have to one story and not another, a sense of an orbit, the orbit of a world that draws me as my own life recedes.
Working in TV and navigating success is a tricky thing. It's easier to navigate the hard work of starting out because you just do anything they let you do, but once you get into an orbit, after the thrusters have pushed you into the orbit, now you have to navigate that orbit. There's no choices when you're starting out. You're just like, "Please, let me do anything." But then it turns around and it's like, "We'll let you do anything".
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.
It changes your perspective to be able to look out the window and see the planet. One of the thoughts that I had when I first got up here was, 'We really do live on a planet, and we are in a solar system, and we are flying through space right now.' I mean, this is something that you know, obviously, but to see the planet - it's amazing.
When we can demonstrate that we can take off horizontally and put something into orbit, then we can begin to talk about increasing the amount of payload. But to say, 'I'm going to do that and put people into orbit' is a real leap.
On 24 October 1944 Planet Earth was following its orbit about the sun as it has obediently done for nearly five billion years.
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!'
If you slid Pluto to where Earth is right now, heat from the sun would evaporate that ice, and it would grow a tail. Now that's no kind of behavior for a planet.
One orbit, with a radius of 42,000 kilometers, has a period of exactly 24 hours. A body in such an orbit, if its plane coincided with that of the Earth's equator, would revolve with the Earth and would thus be stationary above the same spot on the planet. It would remain fixed in the sky of a whole hemisphere ... [to] provide coverage to half the globe, and for a world service three would be required, though more could be readily utilized. (1945) [Predidicting geosynchronous communication satellites]
