I read that on wikipedia yesterday. It's neat, but alot of issues
Problems:
- Over 20.5 light years away, human race won't survive the trip to explore it and learn more of it. Probes would take more then a lifetime to get there, we are going by what we can see thru a telescope, and what we are seeing is currently 20.5 years old too. (learn how light speed works if that statement seems odd).
- They say the tempature can sustain life, there is no proof. There is no proof of water either, just that the condition are good.
- The atmosphere is thin, tempatures at the equator are too hot and the poles are too cold, minimal ring of sustainability. IIRC the water goes to the night side of the planet and freeze, and it goes in the circle as the planet has a day. Something like that.

I must say tho, astronomy is super fun to read about!
