Earth-like planet "might" be orbiting Proxima Centauri, "only" 4 light years away

In interstellar terms, it couldn't be closer: an Earth-like world orbiting Proxima Centauri, the closest sun to our own. Moreover, it's in the system's habitable zone, raising the possibility of liquid water and the conditions to sustain life. But don't get too excited...

Although media reports say the rumored planet orbits in a region thats potentially favorable for life, these smaller stars are less stable, and Proxima Centauri is known to have violent flares at times. Its occasional tantrums have made astronomers skeptical of finding life around red dwarf stars in the past.

However, skepticism has softened some in recent years, and SETI recently launched a major initiative to search for life around 20,000 red dwarfs, as these stars are the most common in the Milky Way galaxy.

One of the most popular locations in science fiction, a habitable world at Proxima Centauri (or, rather, a generation ship headed for it) was most recently tackled in Ascension.
