Pluto Definition and 67 Threads

Calculate the amount of energy required to escape from the surface of the following bodies, relative to that required to escape from the surface of Earth.(a) Pluto I keep on getting the same answer to be .011092137 but according to the website i am working on that is not correct. I used the...

If anyone knows how to calculate the momentum of Pluto it would be great if you could let me know. I am doing a science project and do not understand parts of the project. Thanks!

It's funny how simple math can help you visualize just how far away an object is. Pluto is, at minimum, 2,700,000,000 (2.7 Billion) miles away from Earth. Traveling at "airliner" speeds, say 400mph, a non-stop flight to Pluto would take: 6,750,000 hours en route, or... 281,250 days...

Does anyone know if the Pluto Conjunction was seen by any of the big scopes in Arizona? I know the sky over Southern Arizona (and specifically Mt. Hopkins where the 6.5 meter scope was going to be used to photograph the rare event) was cloudy yesterday evening. This morning it was clear...

http://www.cnn.com/2006/TECH/space/08/24/pluto.ap/index.html "PRAGUE, Czech Republic (AP) -- Leading astronomers declared Thursday that Pluto is no longer a planet under historic new guidelines that downsize the solar system from nine planets to eight." ... :smile:

I read a recently launched spacecraft is going to pluto and is swinging around Jupiter to help it speed up. I don't understand much about physics but surely the planets gravity will give as much kinetic energy as it takes away, once the craft is moving away from the planet. How can it...

NASA'S HUBBLE REVEALS POSSIBLE NEW MOONS AROUND PLUTO Using NASA's Hubble Space Telescope to view the ninth planet in our solar system, astronomers discovered Pluto may have not one, but three moons. If confirmed, the discovery of the two new moons could offer insights into the nature and...

Hi guys, I've been having trouble with this problem and would appreciate just some direction to assist me. I have to estimate the motion of Pluto in "/hour from observations given that the telescope is a 14inch f/11 with an AP7 CCD camera with pixels 24microns on a side. Now we have two...

Interesting article; makes you wonder what we would really define as a "planet." http://news.scotsman.com/international.cfm?id=1707552005

What exactly is Pluto? It says "Pluto is the only known planet which cannot be placed in the terrestrial versus gas-giant planet classification -- it is small, but not very dense." What does that mean? We couldn't live on gas planets because there's no surface there right? But could we live on...

if it transmits and shuts off its transmitter, would the signal still be traveling towards earth?

Ever had a burning desire to send your name to Pluto? Well now you can, thanks to the latest PR idea at NASA- http://pluto.jhuapl.edu/ecard/sendName_ecard_content.html The idea is similar to the one where you could send your name on the Martian Rovers/ on Deep Impact if anyone participated in...

Does anyone know anything about a tenth planet (a planet that orbits outside of pluto's and neptune's orbits) that was discovered a few months ago?

Looking through my old emails, I saw that on Sept 2, the mission was in jeopardy of being canceled. But the Planetary Society and others revived it. http://www.planetary.org/html/UPDATES/Pluto/bond-mikul-thanks.html I may get an ulcer from this on-again-off-again mission.

I have always had a fascination of Pluto, is it labeled as a lost satellite of Neptune, or a planet on it's own because of Charon?
