Earth-like planet found in 39 light-years from the Sun.
The rocky planet nearly the size of Earth, but is characterized by high temperatures has been discovered by astronomers at a relatively short distance from the solar system. A new celestial body told the journal Nature.
GJ1132b exoplanet about 1.2 times larger than Earth. It consists mainly of iron and rock. The diameter of the celestial body - about 15 thousand kilometers, and weight - 60 per cent more. A person standing on the surface, would have felt the force of gravity, 20 percent greater than the Earth's. This is the nearest Earth-like planets - three times closer to the solar system than its counterparts.
However, from its star (dwarf Gliese 1132, about five times less than the Sun) planet separates a short distance: the latter receives 19 times more radiation than the Earth, which is why the temperature of the surface, according to the calculations of astronomers, varies between 136 and 306 Celsius.
Thus, GJ1132b too hot for humans, but may have a dense atmosphere. Scientists believe that it strongly resembles Venus. In its atmosphere prevailing helium and hydrogen. If the last surface was GJ1132b water, oxygen and carbon dioxide can also be preserved in the atmosphere.
Astronomers hope to test these hypotheses by direct observation with telescopes of the next generation - for example, the James Webb telescope (to be launched in 2018). So scientists will be able to see the color of a sunset on the planet - and, consequently, to assess the heat that rises from its "fried" the surface, as well as the wind speed.
Most of the famous astronomers rocky planets much hotter: The surface temperature there exceeds two thousand degrees. Previously, the closest to the solar system Terrestrial rocky exoplanet was discovered at a distance of 127 light years.
"Our ultimate goal - to find a twin of the Earth, but on the way we found a twin of Venus. We suspect that there is an atmosphere reminiscent of Venusian, and we can not wait to sniff it, "- said study co-author David Charbonneau (David Charbonnneau) from Harvard.
