Based on these statistics, the astronomers conclude that the nearest potentially habitable Earth-sized planet is likely to be a mere nine light-years away.

Using facilities operated by the European Southern Observatory and other telescopes, the international team discovered the planet, called Proxima b, which orbits Proxima Centauri, the closest star to the Solar System. This planet is about 1.3 times that of the Earth and has a temperature suitable ...
Planets in the habitable zone around Proxima receive an average dose of X-rays about 500 times larger than the Earth, and 50,000 times larger during a big flare, according to NASA.
Years always refers to Earth years, and an AU is an astronomical unit, the distance from the Earth to the sun. Ly are of course light-years. A rough-and-ready formula for the habitable zone is to take the square root of the luminosity, and take 95% of this figure as the inner li...
planet, and it completes 1 orbit in 11.2 days. On the deductive side, because of its mass, it is believed to have a rocky surface much like the Earth’s. And because it orbits its star in the habitable zone — where temperature is neither too hot nor too cold for liquid water to ...
It might be cold, inhospitable and all but invisible but the new planet has one thing going for it: it's really close. The only known exoplanet closer to Earth was discovered in 2016 orbiting one of a cluster of stars in the Alpha Centauri system, just over four light-years away. ...
It’s also worth pondering how our Sun might appear to any inhabitants of these neighboring systems. With its flares and rich diversity of planets, it would likely be an enticing object for any extraterrestrial astronomers — especially those based around Wolf 359, from which Earth appears to tr...
"In this case, Proxima b would be covered by a single, liquid ocean 200 km deep," said the CNRS. "In both cases, a thin, gassy atmosphere could surround the planet, like on Earth, rendering Proxima b potentially habitable," it concluded. © 2016 AFP...
