Earth-like planet found !!!

here is another link

www.msnbc.msn.com...

and like gazrok was saying it's the only rock planet to be discoverd outside of our solar system

Hi All, "ThatsjustWierd" posted, that on this new planet we would live to be thousands of years old. Wouldn't it be the opposite since it orbits its star in such a short time wouldn't we age super fast!?

Can someone explain how our internal clocks are affected by the time it takes a planet to circle its sun? I would think our genes are programmed to age in the time it takes to reach old age, not the amount of time it take sour planet to circle to the sun. 1 year as i see it would be our interpretation of time to fit our aging process.

Any thoughts?

I think maybe you misunderstood the joke, I think they meant that because it revolves around the star so fast, basicly just 1.9 "earth" days is one year there, that if you lived to 75 "earth" years old there you would literally be thousands of Gliese 876d (the new planet) years old but still only 75 in earth years. It was a play on time, not physics or physiology.

But let's figure it out anyway:

75 earth years = 27375 earth days + roughly 19 extra days for leap years.

1.9 earth days = 1 year on the new planet

27375 + 19 = 27394 / 1.9 = 14417.89

So you'd be roughly 14,418 Gliese 876d years old or 75 Earth years old, but the same age regardless, just a different measure of time. Consider it the diferrence between saying you are 30 years old or 10950 days old, it's the same either way.

thats pretty interesting, too bad its really hot... Im looking forward to someone finding another, more human-friendly planet

If no one else has noted this, its 'earth like' in that its not a gas giant.

Its 7 times the size of earth, far closer to its star, and the surface temp is starts are around 400 degrees and goes up from there. Its a big discovery, its the first rocky planet outside of this solar system, but claims of 'earth likeness' are a bit overhyped in the media.

The next solar system over has at least one earth-like planet!

its not the next system over, the closest star to earth is Alpha Centauri, which is a planetless binary system thats about 3-4 light years away. The system this planet is from is fanatiscally far away.

This is probably just semantics, but to clarify:

1. Alpha Centauri is the closest star system to Earth. It is a three star system containing Alpha Centauri A & B, and Proxima Centauri.

2. The closest star is actually Proxima Centauri, classified as a red dwarf.

3. The Alpha Centauri system is 4.36 light years from Earth.

4. Distance measurements for Gliese 876 vary between 15 and 15.4 light years from Earth.

Our space shuttle goes approximately 17,000 mph after reaching open space. The speed of light is 186,282 mps.

Traveling at our current speed:
Alpha Centauri System= 172,107.2 years
Gliese 876= 592,111.9years

Both of these are "fantastically" far away by today's standards. Following the same reasoning, if we ever accomplish speed of light travel, both stars would be reachable in a relatively short amount of time. All though claims of earthlike may be over hyped, I do believe that this is a very exciting discovery!

I would be prepared for as the technology and identification experience improves, we discover a few smaller hunks of rock in this same system.

Another thing to think about.. it took them a few years to rule out all other possibilities and come forward with a public announcement of discovery. Maybe a true Earth 2 has already been detected, and the lucky astronomer just has a few more years of research before they can be sure.

It's only "Earth-like" if you consider earth-like conditions to be 2-5G surface gravity and 400-700 degree surface temperatures to be "Earth-like."

It is a rocky planet instead of a gas giant though, so it is progress in planetary detection.

As democracy is perfected, the office of president represents, more and more closely, the inner soul of the people. On some great and glorious day the plain folks of the land will reach their heart's desire at last and the White House will be adorned by a downright moron." - H.L. Mencken (1880-1956)

Somewhat off-topic here, but this is where I saw the signature. There is no "perfect" democracy; every "Democracy" in history has failed, because a Democracy is the first step toward Communism. Thankfully, America is a Constitutional Representative Republic, although the left has been taking us towards a Socialist/Marxist country for the past 45 years.... since Roosevelt. The quote you mention by Menchen reached it's prediction in 1992. Hopefully, now we can begin the work to become a Republic again. Also, the quote by Ghandi... geee.... all we had to do was lay down our guns, tell Hitler we were his friend, and he would have let all those people live; If only we had known.....
