    Livable Alien Planet Finally Discovered

    Alan Boyle writes: Astronomers say they've found the first planet beyond our solar system that could have the right size and setting to sustain life as we know it, only 20 light-years from Earth.

    "My own personal feeling is that the chances of life on this planet are 100 percent," Steven Vogt, an astrophysicist at the University of California at Santa Cruz, told reporters today. "I have almost no doubt about it."

    The discovery, published online in The Astrophysical Journal, is the result of 11 years of observations at the Keck Observatory in Hawaii. Astronomers participating in the Lick-Carnegie Exoplanet Survey detected the planet by tracking the faint gravitational wobbles it produced in its parent star. Now they say there may well be many more planets out there like this one.

    "The fact that we were able to detect this planet so quickly and so nearby tells us that planets like this must be really common," Vogt said in a news release.

    From the actual article -

    However, this does not mean the planet is habitable, or even very Earthlike. It may not even have any water on it at all. For now, we canít know these things, so beware of any media breathlessly talking about life on this planet, or how we could live there.

    There are some things we can speculate on with some solid footing. The orbital period of 37 days puts it pretty close to the star Ė since the star is a red dwarf, itís cooler than the Sun, so being closer doesnít necessarily mean you overheat. But it does mean the star exerts strong tides on the planet, which have the effect of slowing the planetís rotation until it equals the orbital period. This has almost certainly happened to this planet, so in other words, one day on this planet = one year, and the planet always shows the same face to its star like the Moon does to the Earth.
    Still it does contradict the old notion that any planets in the "Goldilocks zone" are necessarily hundred of light year away. Interesting to say the least!

    Upon further review of the listings on Zillow?

    The planet in question has a home owners association - which makes it unsuitable for humans.
