For example, a space telescope, NASA «Kepler» only opened in March 2009 more than 2.3 million potential exoplanets. However, only 100 of them were established after a more detailed examination.

The first exoplanets were called celestial bodies, resembling Jupiter in size and inflamed because of its proximity to their parent stars. However, as technology advances, astronomers began to notice the smaller and fainter celestial bodies, which, however, by their characteristics more like Earth. In the past year, "Keller" has found a planet that is 2.4 times larger than Earth. It probably has water and possibly life. None of the alleged exoplanets can not compare its size to the Earth. Each of these heavenly bodies is much larger planet. In addition, they are too close to its parent star. So scientists are screened out those planets that are in the so-called. The "habitable zone," where not too hot and not too cold for that could harbor life. If you get more information, visit our site: Write my paper
