Information about 'Second Earth'

Astronomers have discovered a planet with many similarities to Earth. The planet can orbit its host star with the same distance from Earth to the sun.

NASA announces information about "Second Earth"

The planet is located in the Goldilocks region , where life can exist because the temperature is not too hot or too cold for water to exist in liquid form. Moreover, its aging master star is similar to the sun, AFP said on July 24, the announcement of the US Agency for Aeronautics and Space (NASA).

The planet , 1,400 light-years from Earth, could give a glimpse of the future of the Earth, according to scientists. The planet, called Kepler 452b, was discovered by NASA using the Kepler telescope.

'Kepler 452b has an orbit close to the Sun's' close relative ', but it's 1.5 billion years older,' according to NASA.
Scientist Doug Caldwell of the Kepler project, which specializes in the search for extraterrestrial life, said that if this is a rock planet, it means that it is entering the greenhouse phase, the temperature from the host star will evaporate. water from the lake and ocean on Kepler 452b forever.

Mr. Caldwell said what happened at Kepler 452b now is what will happen to Earth after more than a billion years, when the sun gets older and becomes brighter.

The Kepler project was started in 2009 to look for life in extrasolar planets. Currently, thousands of planets have been discovered. On July 23, NASA announced the list with 4,675 planets of this type found by telescopes.

The new data includes 12 'candidates ' that are smaller than Earth twice and orbiting around host stars and can live. Among these 12 candidates, Kepler 452b was confirmed as the first planet.
