We're a small step closer from interstellar travel, and that's good. In an "evacuate Earth" scenario, such a close target would be invaluable.

Back in the 1980s there was a book published by Stewart Cowley with lots of fantastical science fiction paintings and a made-up future history narrative to link them all together. I still have a copy.

In that narrative, sometime during the 21st Century Earth gets into an interstellar war with the Proximans. I really hope the book isn't quite as accurate in predictions; human colonies on Mars get hit really hard with Proximan nukes.

The yellowish-colored fighters on the cover art are supposed to be Proximan spacecraft, shown here escorting a Terran starship after the peace treaty is signed:

I happen to own a copy of the same book! In the German version the editor is 'Commander' Stewart Cowley, a member of the Terran Space force during the Centauri wars. :) The book was my primary source of imagination on spaceships in the pre-internet era!

I looked up Cmdr. Cowley last night and it seems he maintains a website: http://www.greatspacebattles.com/

so it's a possibly rocky possible planet with a 12 day year in a zone that makes liquid water possible (if any there!), no knowledge about radiation - immediately it's "earthlike" . . . I dunno - leave it to the Proximen

(and we got thrown out of Eden . . .)

I know we will never visit this planet in my lifetime but im glad that the current state of technology will allow us to get a decent snapshot of this planets conditions. Within a decade or two we would know the composition of its atmosphere, its color, and if were lucky, a rudimentary map of it.

Proxima, I think, is drawn too small there.
In comparison to Sol, it should be something like at the right side of the image:

This is amazing, I dont understand why its not in first page of all newspapers. An exo-planet in the most near system, in the habitable zone, and with a mass similar to Earth. Have you seen the simulation of temperature distribution in the link sorindafabico provided? I would even say this is more important than New Horizons reaching Pluto.

If it were confirmed to be Earth-like. It is not even confirmed whether it has an atmosphere or not.

It seems to have liquid water or at least a high chance of it. Which means a minimal atmosphere is realistic. Must not mean the atmosphere is the same as on Earth, which is the product of life messing with it.

Given how close it is, I'm quite sure we can study it in relative detail remotely in the next few decades. Also, some radio eaves-dropping might be useful.
