Are you talking about Gliese581g? All i know about it is that its weather is extreme but livable. We dont even know that much about it just that we THINK its X au's from its sun which has X diameter and is a red dwarf i think and so with a few calculations we can concur that it might be inhabitable. Thats about all i know, and im probably wrong, but i dont feel like doing research or typing correct sentences. (x

It's about 20 light years away. Even if we do find a habitable planet, we still have to figure out how to get there. Sure, we could hibernate for 20 years, but that's assuming we develop some sort of light-speed travel which would require exponentially higher amounts of energy as you approach the constant. I think if we keep neglecting problems on this world in favor of searching out other planets, then we will not even exist long enough to colonise other planets.

Of course, if solar sails ever become wildly used, we have possibly limitless energy to propel our crafts. All from photons alone.

Since Gliese 581 is a a red dwarf star with spectral type M3V,

Gliese 581 g is just 0.50 AU from it's parent star.




Compare the Suns habitable zone with Gliese 581's.

The disadvantage about solar sails is that they take months or YEARS to build up speed. we need a more efficient way of propulsion.


And have you heard of the Mu Arae System? for some reason NASA isn't publishing the the news on it's discovery.
