It was named as Kepler-452B and is in the constellation Cygnus.
Thanks to observations made with the Kepler space telescope, NASA could detect the closest planet to Earth since it started to search for exoplanets with this powerful instrument in 2009.
A year ago it has discovered planet Kepler-186F but it did not share the characteristics of the new ‘cousin’ of the Earth.
Kepler exoplanet-452B is showing more similarities with our home planet. This is bigger than the Earth by 60% and is 1,400 light-years away in the constellation Cygnus with an approximate age of 6,000 million years. Time orbit around the sun is 385 days and the distance between them is only 5% larger than the Earth and the sun. Although not yet have evidence of their mass and composition, scientists are confident of it as a rocky planet.
“In the 20th anniversary of the discovery it proved that other suns host planets, exoplanets Kepler Explorer has discovered a planet and star that resemble Earth and our sun. This exciting result brings us one step closer to finding a 2.0 Earth, “he said in the official statement of John Grunsfeld, associate administrator of the division of NASA missions at Washington.
Jon Jenkins, leader in the analysis center of the Kepler space telescope, scientist, was thrilled with the characteristics of Kepler-452B in order to find life outside our Earth: “It’s amazing to consider that this planet has spent 6,000 million years in the habitable zone of its star, rather than the Earth. That is a substantial opportunity for life to arise, there must be all the ingredients and conditions for life to exist on this planet. ”
When there are other 4,696 exoplanet candidates that the Kepler mission will study in the future.
