It's called Gliese 581 C,
5 x earth size, about double the gravity.
Probably tidally locked.
It's only 20.5 LY!! You can see its star with a telescope.
Watery, 0-40 Celsius...big, roomy...
After those Aussie murders I'm packin' my bags to get away from the rest of you psychos!

"sauna stories? There are no 'sauna stories'.. I mean.. sauna is sauna. You do by the laws of sauna." -P.
And it's actually more like 1.84 g for all you 'on the edgers'.
It all depends on whether or not it is primarily a water or silicate world. (density)

It's a shame that it's so far. If it was closer, say at around 5-7LY, it's existence could've added some fuel to FTL research. Or at least research on conventional nuclear powered probes that can reach a fraction of c. Orion maybe.

I'm looking on it from the point of view of exploring it.
5-7 ly is feasible if you achieve c fractional velocities. I mean, we're waiting 9 years for a Pluto probe to reach it's destination and all for a flyby, so waiting 20-30 years for that is reasonable.
But 20ly? Nah. No one would bother sending anything without FTL.

I disagree. There's no reason it wouldn't eventually be visited even if the trip took 100 years. By the time humanity was ready to build such interstellar probes people will probably be able to remain physically young long enough to contemplate such a journey anyway. 20 light years is about as close as anything outside the alpha centauri system will ever be.
Well, there are roughly 70 G-type (like Sol) and K-type (slightly cooler) stars within 40LY of us, so to find even one marginal planet orbiting an M-type star (red dwarf, cooler still) within 20LY is a fantabulous discovery all by itself. I would think the fact that it's there orbiting a type of star we considered less likely to have such a planet would spur a greater desire to get there on its own merits. Anyway, we're right back to that thread we had some time ago about how to reach nearby stars without FTL. I maintain that ~20LY is doable with a generational ship using current technologies, but we would need a greatly expanded industrial capacity for the prep work.
The cake is NOT a lie. It's so delicious and moist.
The Weighted Companion Cube is cheating on you, that slut.
Be funny if a more modern ship passes them by 20years after take off
Learn to overcome the crass demands of flesh and bone, for they warp the matrix through which we perceive the world. Extend your awareness outward, beyond the self of body, to embrace the self of group and the self of humanity. The goals of the group and the greater race are transcendant, and to embrace them is to acheive enlightenment.

They might expect that would occur and in that case wait 20 years instead of going. But after a hundred years or so of waiting and no huge improvements in travel time I imagine they might be willing to risk being overtaken on their trip there.

I'm talking about the next few decades. If you're talking centuries, then you're right.
