The planet was discovered by the Kepler telescope – from him also took her working name. Kepler-452b in the constellation Cygnus lies 1400 light years from us, and its diameter is larger than the diameter of the Earth by approx. 60 percent.
Earlier managed to discover the worlds of roughly this size, but Kepler-452b also revolves around a star very similar to the Sun, as well as at a distance similar to that separating the Earth from our star.
Given the size of the planet, scientists estimate that it has a rocky constitution – like Earth. The conference, which announced the discovery, the researchers said that using the telescope has discovered 11 other new planets in the ecosphere.
cousin year on the planet lasts 385 days
What else do we know about Kepler-452b? While the planet is larger than Earth, its orbit is very close to ours. The full lap star takes her 385 days. Same star – Kepler-452 – has six billion years and is about one and a half billion years older than the sun. It is also slightly bigger and brighter than our star, but their temperatures are similar.
As shown in the above graphic, the same planet Kepler-452 is relatively small planetary system, located in the orbit of Mercury.
“6 billion years gives a good chance for the existence of life”
– We can treat this planet as older, bigger cousin of the Earth, which will allow us to better understand Earth development environment – said Jon Jenkins, an analyst at NASA working on data from Kepler telescope and head of the team that discovered the new planet. – Today the Earth is a little less lonely. He has a new friend on the estate – he added Jenkins.
– The fact that this planet for six billion years is the ecosphere its star, is very inspiring. Such a long time will give ample opportunity to the existence of life on the planet, if you were there all you need – explained the scientist.
Of the 12 newly discovered planets circling four around stars like “M” – they are much smaller and cooler than the sun. It is also the most numerous type – they are approx. 85 percent. all the stars in the Milky Way.
Seven other planets is in the systems of stars of “K” – relatively smaller and cooler than ours. On the other hand Kepler-452b orbits the star of “G” – the same which includes the sun. Types of stars is determined by the spectrum emitted by the light.
How do we discover new planets? Scientists measure the “pulse” of the stars
How scientists are able to discover a planet away from us hundreds of light years? Kepler telescope, which was used to find new celestial body, measuring the brightness of stars.
Every time when the planet crosses the line between the telescope and the star, the brightness decreases slightly. Presented graphically, it reminds a bit EKG – a kind of “pulse” of the star. Repeated “pulse” allows you to specify the orbit and size of the planet.
The Kepler telescope has six years looking for distant worlds, with conditions similar to those prevailing on Earth.
