This is the closest exoplanet from the closest star to our solar system. There is a possibility of habitable life.
"The habitability of Proxima Centauri b has not been established,[12][13] since the planet is subject to stellar wind pressures of more than 2,000 times those experienced by Earth from the solar wind.[12][27] This radiation and the stellar winds would likely blow any atmosphere away, leaving the undersurface as the only potentially habitable location on that planet.[28]
The exoplanet is orbiting within the habitable zone of Proxima Centauri, the region where, with the correct planetary conditions and atmospheric properties, liquid water may exist on the surface of the planet. The host star, with about an eighth of the mass of the Sun, has a habitable zone between ∼0.0423–0.0816 AU.[1] In October 2016, researchers at France's CNRS research institute stated that there is a considerable chance of the planet harboring surface oceans and having a thin atmosphere.[29] However, unless the planet transits in front of its star from the perspective of Earth, it is difficult to test these hypotheses.
Even though Proxima Centauri b is in the habitable zone, the planet's habitability has been questioned because of several potentially hazardous physical conditions. The exoplanet is close enough to its host star that it might be tidally locked.[30] In this case, it is expected that any habitable areas would be confined to the border region between the two extreme sides, generally referred to as the terminator line, since it is only here that temperatures might be suitable for liquid water to exist.[31] If the planet's orbital eccentricity is 0, this could result in synchronous rotation, with one hot side permanently facing towards the star, while the opposite side is in permanent darkness and freezing cold.[32][33] However, Proxima Centauri b's orbital eccentricity is not known with certainty, only that it is below 0.35—potentially high enough for it to have a significant chance of being captured into a 3:2 spin-orbit resonance similar to that of Mercury, where Proxima b would rotate around its axis approximately every 7.5 Earth days with about 22.4 Earth days elapsing between one sunrise and the next.[14][34][35] Resonances as high as 2:1 are also possible."
What's also interesting is that there is a program set up to launch there and send info back to earth using miniature unmanned spacecraft called StarChips which would travel at 20% the speed of light and would take 20 years to get there and then 4 more years to send the info back to Earth.
