Possibly habitable planet found

Postby azazul » Wed Apr 25, 2007 12:57 am

Scientists have found a planet orbiting a red dwarf only 20.5 light-years away, that is in the habitable zone.

Thanks, azazul. That's fascinating.

How long before GLP is talking about us being invaded by Gliesians?

There has already been one claim there that it was Nibiru. Apparently, they don't know how far 20.5 light years really is.

Oh, but that 20.5 light-years is only 27 yards, 3 inches if you travel through the same fifth dimension portal the Reticulans use.

This is kind of exciting. Five Earth masses, and with a temperature range that could support liquid water. We're getting closer and closer to finding Earthlike worlds. I wonder if our first discovery of an extraterrestrial civilization isn't going to be a next-generation orbital telescope observing an alien city on a planet whose atmosphere looked like post-industrial Earth's.

Well, according to the NBC Nightly News, if we could travel at 186,000 MPH we could reach this new planet in only 21 years.

That can't be right. According to my equations, that's much slower than speed of light.

3600 times slower if I'm not mistaken. News media. :roll:

Of course we should remember that the 4.8 Earths figure is actually m/sin(i), meaning until the planet's inclination relative to our sky is known, all we have is a minimum mass figure. I wish I knew what the upper limit is for a rocky planet but the only references I was able to find were Wikipedia mentioning several planets including one of around 13 Earths that could be either rocky or gas giant. :?

That figure seems approximately correct by my calculations...

This could open up a whole new round of debates to go along with the Pluto what is a planet controversy. Its believed that Jupiter has a rocky core about the size of Earth. So, at what point does a terrestrial, rocky planet, aquire enough atmosphere to be called a Jovian planet? We've been fortunate in our little solar system.

Our planets have been neatly divided into terrrestriljovian and odd balls Like Pluto. As more planets are discovered that don't fit into our preconcieved notions of what type of planet they ought to be, I can see page after page of debate, especially over at BAUT.

To be fair, it's only one letter off. Astronomy is also not taught well enough, nor is physics.

My Trekkie friend Katie is excited that they finally found another M-Class planet. :lol:

If it was written, I would give them the benifit of the doubt. But it was a reporter who actually said, "miles per hour."
