That's right. We've all been waiting for it and it's finally here.
A planet that in theory - can house people! It's called the Gliese 581d, it's about double the size and seven times the mass of Earth and the temperature is just right, because water doesn't vaporize nor does it freeze!
There is a chance a human-like species already live there, but I don't think anyone will ever find out. You want to know why? It'll take us roughly 300.000 years to reach it, being 20 lightyears away. Yeah, I know it sucks. :)
If we ever DO get there, it will really weird. . And thanks to it's mass (no offense Gliese) surface gravity is double Earth's.
