It's similar to the sun, scientists say not only her sister but her twin children.
A group of astronomers have detected a star like a carbon copy of ours.
It has the same temperature and lightness, very similar chemical composition and almost identical, about 4,500 million years ago.
Twin stars, called HD 186302, It has extended 184 light years and scientists will investigate the place of birth of the sun to keep them mysterious.
"Since there is no more information about the past of the sun, it helps us to learn some of these stars in order to understand the galaxy and the conditions that make up the sun," he said. Vardan Adibekyan, Astronomer of the Astrophysics and Space Sciences Institute of Portugal.
Astronomers have long sought out the sun's sisters, that is, the stars They were created in the same gas and dust cloud du ours.
So far, few candidates have been identified as solar siblings.
It is known that the stars were formed into one of these thousands of childhood or stars, but when the Milky Way disappeared, it is very difficult to find them.
For example, his colleagues used a sophisticated method in the research.
"In collaboration with Patrick de Laverny and Alejandra Recio Blanco, we have obtained a sample of 230,000 spectrum AMBRE project from the French Riviera Observatory (the European Observatory and the Observatory of the French Riviera)."
Scientists have a large sample of stars obtained through the satellite theme.
One of the biggest questions that astronomers will try to answer is whether a planet around HD 186302 can take life.
"They show some theoretical calculations there is a minority of probabilities of life It could spread to the ground other planet or exoplanetary system In the last bombardment era, "said Adibekyan.
A bombardment of around 4,000 million years ago was caused by the bodies of the Solar System caused by large asteroids.
The possibility of detecting life signs in an exoplaneta of the sun's bikini.
"If they are lucky and our solar system has a planet and it's a fast planet, it's a vibrant space, and finally, if they have been infected with the seeds of life on planet Earth, then what could be the dream: Earth 2.0, Sun 2.0 orbit. "
