"As for similarities with Earth and, especially, on the suitability for life, they went too far, of course. At the moment, we can only be sure that this planet does exist. It is, perhaps, a part of the Proxima Centauri, but so far the experts have no solid conviction. It is interesting, that it is indeed the closest exoplanet to us. But as of today, more than 2,000 similar systems, although located further, have been discovered. And every time, when they discover one more, the media is ready to report that there is a planet similar to Earth, and it is possible that the little green men are there," Leonid Ksanfomaliti told RIA Novosti.
He added that the star Proxima Centauri, which Proxima-B orbits, is quite cold and unstable and therefore "it would be quite hard to survive for us, to put it mildly."
Earlier in August, another distant planet that orbits a star 39 light years away from Earth which could have oxygen in its atmosphere was discovered.
