| Video Discription | Astronomers have spotted the closest thing yet to the first true ‘Earth twin’ — a small planet orbiting the bright star Kepler 452, at a distance where liquid water could exist. Astronomers using a telescope "Kepler" discovered exoplanet, the surface of which presumably have liquid water. This is the first Earth-like planet that is in the "habitable zone" of a star similar to our sun. On the opening of the mission, experts said at a press conference, and briefly with the study can be found in the material Nature. The planet is called Kepler-452b, it is the second of the exoplanets discovered the star Keprler-452, located in the constellation Cygnus. The distance to the star is 1,400 light-years, it is somewhat brighter than the sun. According to scientists, the mass of Kepler-452b 60 percent more than the mass of the Earth. This makes it more promising exoplanet analogue of Earth than previously discovered worlds orbiting cooler stars. Similarly measure the mass novoobnaruzhennoy "Earth" fails, but the simulation suggests that it is about five times heavier than Earth. Year on Kepler-452b lasts 385 days. Age of the star around which ekspoplaneta is 6 billion years old, making it the 1.5 billion years older than the sun. Presumably, the planet has the same age. QaR3jguzEmA |
