Astronomers discovered a little exoplanet, which has less dimensions and weight, than the smallest planet Mercury in the solar system. The planet Kepler 37b moves around the star in Lira constellation every 13 days. It has 210 light years distance from the Earth. This planet is stone planet, and has approximately 427 Celsius temperature, because of that fact, there cannot go any speech about life.The moon-size Kepler 37b is so close to its parent star, at just 0.10 AU, that it likely has no atmosphere or liquid water on its surface.Kepler 37b was discovered by telescope “Kepler”. The $600 million Kepler mission launched in March 2009, and has found more than 2,740 candidate alien worlds so far. Just 114 of these potential planets have been confirmed by follow-up observations to date, but mission scientists estimate that more than 90 percent will end up being the real deal. The spacecraft searches for small dips in stars’ light caused by orbiting planets that pass in front of them periodically, dimming their brightness.
