NASA | Charon at 40: The Discovery of Pluto’s Largest Moon
new horizons,pluto,charon,nasa
The largest of Pluto’s five moons, Charon, was discovered on June 22, 1978, by James Christy and Robert Harrington at the U.S. Naval Observatory in Flagstaff, Arizona.
Read the story:
Charon was discovered only about six miles from where Pluto itself was discovered at Lowell Observatory. They weren’t even looking for satellites of Pluto – Christy, examining a series of grainy telescope images, trying to refine Pluto’s orbit around the Sun.
Christy and others tell the story of this amazing scientific find, which fueled Pluto’s transformation from a telescopic dot into an actual planetary system – and a source of many discoveries to come.

I can name all five of Pluto’s moons
Big whoop. Pluto is no longer a planet, so Charon is no longer a moon. They’re just two large asteroids gravitationally bound to each other. Reclassify Pluto as the 9th planet and I’ll reconsider my position on whether Charon can be called a moon.

What a wonderful story!
What is the name of the song
I am so so happy that they re-instated Pluto as a planet, I still don’t understand why they changed Pluto to a dwarf planet because it had all the qualifications to make it a planet giving the information. (correct me if I am wrong please).

Fake news
imagine this story way…
It can’t be a mini solar system. The word solar implies sun. There’s no sun in this mini system. And since Pluto is no longer classified as a planet, why the hell are we even looking at the damn thing. This is ridiculous. 40 seconds in and already NASA is dis informing us. It’s not a mini solar system if there’s no mini sun to go along with it
It’s a sweet story but we should be careful not to misinform, NASA. You can’t have a mini solar system without a mini Sun
This story would’ve been perfect, if the moon was named after someones mother-in-law.
Only then, a name synonymous /interchangeable with the word Death, would fit like a glove.
I’m glad I watched that.
Space force?

Good job NASA!!
So amazing to see the guy who discovered her see it in detail
“A lot of husbands promises their wifes the moon, but he delivered” 😀
And I thought different for so many years, awesome story.
If earth is flat, how about the gravitational?
amazing story, amazing video !
The human side of your work, many thanks
This is charming!😍
Nice video ! 👍Salutations
NASA 💗
agencia espacial é d+ amo todos os filmes quero trabalhar lá.
Why does the Navy have an observatory in a landlocked city like Flagstaff, AZ?
Very interesting, thank you and Jim!
Why such a big brouhaha about Pluto? Is it because it’s the only planet (dwarf planet) discovered by America?
Awesome
Hi NASA! How it’s going?
Wow I never knew that. That’s an awesome story. 😊🌛
Nice video
I wish to work in NASA or ISRO at least one time in my life
I love that story. What a great legacy.
Love this informative story.
