Spacecraft Kepler discovered two exoplanets similar to Earth more other

New planets, which the researchers data from the Kepler said at a conference of the American astronomical society (American Astronomical Society in Seattle, six. They are all small and moderately warm, but two, called Kepler 438b and Kepler 442b, both in size and position in the habitable zone of their stars, are now the most earth. Scientific publication about these planets will appear in The Astrophysical Journal. Both planets removed from us for many hundreds of light years and orbit of the stars smaller and less bright than our Sun. Like most discoveries apparatus Kepler, they were discovered by the transit method – the fall of the luminosity of the star during the passage of the planet in front of its disk. The transit of the planet allows astronomers to determine the size, orbit and exposure to radiation from the star. According to the data obtained Kepler 438b size exceeds the Ground by 12 percent and receives 40% more starlight. Kepler 442b more Land by 30 percent, and the stellar radiation this planet gets 30 percent less. The temperature on both of these spherical bodies slightly higher than the two previously discovered by Kepler candidates for Exo-Earth, planets Kepler 186f and Kepler 62f, each of which received much less stellar radiation and this parameter was closer to Mars.

The apparatus researcher Kepler was launched by NASA in 2009 to study the sky, which is about 150 thousand stars, to detect doubles Earth – planets the same size as ours and with the period of revolution around its star in 365 days. The search was given more than three years since the reduced luminosity of the star, in addition to passing in front of her planet, may be caused by other factors, and astronomers, in order to ensure that shading caused earth planet had to see the periodic transit of a celestial body not once, not twice, but three times. However, the plans of researchers influenced by sun-like stars, their luminosity was unstable, it took additional observations, and because in 2012, the mission was extended. The work of Kepler, was completed only in the spring of 2013 with the failure of stabilizing equipment. Currently analyzed archival data. Commenting on recent discoveries, study co-author David Kipping (David Kipping of the Harvard-Smithsonian astrophysical center (Harvard-Smithsonian Center for Astrophysics) emphasizes: “we cannot say with confidence that these planets really inhabited, we are only talking about the fact that this is a very promising candidates for habitable planets”.
