Astronomers have discovered Icy world in a binary star system

Astronomers have discovered a planet in a relatively close binary system in about 3,000 light-years away, the distance from its host star with the distance of the Earth is comparable to that of the sun. Experts see this as evidence that can form on Earth-like orbits in such close binary systems planet.

 In our Milky Way galaxy there are billions of stars. In the search for the "second Earth", so after a planet whose mass, size and orbit is roughly equivalent to that of our home world, an attempt is therefore to focus on systems in which actually the probability of finding such a planet, particularly is high.

Binary star systems, particularly systems where the distance of the two stars is relatively low, yet did not form ausreichsten places for such a search. A now imagined Fund may imply that scientists need to revise this idea a little.

In about 3,000 light-years away Astronomers have now detected namely a planet with twice the mass of the earth in a binary star system, which is a similar distance away from one of the two stars, as the earth from the sun.

Since it is the star, however, is a red dwarf star, which is about 400 times fainter than the Sun, are likely to prevail on the distant world only temperatures of just -213 degrees Celsius. The second rating of the system has a star from the first distance corresponding to the distance of the Saturn from the sun. Even with this, there is a dwarf star.
