И еще более... // Superhabitable!

[shkrobius]

...Scientists have developed a language that neglects the possible existence of worlds that offer more benign environments to life than Earth does. We call these objects “superhabitable” and discuss, which worlds tend to be more habitable than Earth. The principle of mediocracy cannot be used to logically explain why Earth should be a particularly habitable planet or why other inhabited worlds should be Earth-like. Considering a range of physical effects, we conclude that [superhabitable world] will tend to be slightly older and more massive than Earth and that their host stars will likely be K dwarfs. This makes Alpha Centauri B, which is a member of the closest stellar system to the Sun an ideal target for searches for a superhabitable world.
