An artist's impression of Kepler 452b, the most Earth-like planet ever discovered According to Jon Jenkins, the Kepler data analysis lead at NASA's Ames Research Centre, this means it's possible that it hosts life on its surface, or at least could have at some point in its history. According to Jon Jenkins, the Kepler data analysis lead at … Image via SETI Institute/Danielle Futselaar. It's slightly warmer than Earth, slightly larger, could have liquid water on the surface and it's 1,400 light years away, Find your bookmarks in your Independent Premium section, under my profile. He was always with his group. The illustration represents one possible appearance for Kepler-452b -- scientists do not know whether the planet has oceans and continents like Earth.

If Kepler-452b had the same mass as Earth it would be on the verge of experiencing the runaway greenhouse effect and the loss of its water inventory. The added light and heat energy that the planet receives from the star not only means it is slightly warmer than Earth, but could also mean that plant life could thrive there. The habitable zone is a region around a star where temperatures are right for water—an essential ingredient for life as we know it—to pool on the surface. Kepler-452b has a probable mass five times that of Earth, and its surface gravity is nearly twice as Earth's, though calculations of mass for exoplanets are only rough estimates. Kepler 452b "is the closest thing we have to another place somebody might call home," Jon Jenkins, Kepler data analysis lead, said in a news conference call on Thursday. Due to its size and age, it's likely that it is a rocky planet, meaning it could have a volcanic system under its surface. As a result Kepler 22b is considered as one of the best exoplanet candidates for habitability. Kepler 452b is an earth-like planet orbiting a sun-like star, Kepler-452, located in the constellation Cygnus. If Kepler-452b does support the existence of water there is a chance that the planet could even play host to oceans. According to John Coughlin, a researcher at the SETI Institute in California, the Kepler team worked with geologists to find out the make-up of the planet. Want to bookmark your favourite articles and stories to read or reference later? If it's too far away, it will be too cold. Kepler-452b has a diameter 60 percent larger than Earth and is considered a super-Earth-size planet. Its diameter is 60 percent larger than Earth’s, which means it likely has a rocky surface. The Goldilocks Zone is where the temperature is optimum for life to exist and also for water to exist in liquid state. As a result, the planet receives a similar amount of radiation as we do from the sun; just 10% higher. An artist's impression of Kepler 452b, the most Earth-like planet ever discovered, This image compares the size of Earth with the size of Kepler 452b, Kepler 452b was named after the telescope that spotted it, the Kepler space telescope, This artist's impression shows what the surface of Kepler 452b could look like, with active volcanoes and liquid water, The sweep of NASA Kepler mission’s search for small, habitable planets in the last six years, A graphic of the crafts that have carried out Exoplanet missions, This size and scale of the Kepler-452 system compared alongside the Kepler-186 system and the solar system. The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone — the area around a star where liquid water could pool on the surface of an orbiting planet — of a G2-type star, like our sun. Kepler-452b isn’t the first exoplanet found in a habitable zone. Kepler 452b "is the closest thing we have to another place somebody might call home," Jon Jenkins, Kepler data analysis lead, said in a news conference call on Thursday. In addition, water outgassing from the mantle reservoir can compensate for surface water loss and extend the time of water existence on Kepler 452b. Kepler-452, stellar object 1.1. If a planet is too close to its star, it will be too hot to host life. Kepler-452b is the most Earth-like planet ever discovered, a place with just enough sunlight to possibly support the crops and house plants of life forms like ourselves. Light from the Sun takes around eight minutes to reach Earth, so naturally, a trip to Kepler 452b would take an incredibly long time. It means that we could inhabit this planet someday in far future. Jon Jenkins told the press conference: "The sunshine from Kepler's star is very similar to sunshine from our own star, and plants could be able to photosynthesise just the same. Kepler-452 b, planet, semi-major axis: 1.046+0.019−0.015AU Due to the sheer scale of this comment community, we are not able to give each post the same level of attention, but we have preserved this area in the interests of open debate. -- scientists do not know whether the planet receives a similar amount of radiation as we know thousands.
