Amateur astronomers have made a startling discovery – a planet with four suns.
– It is an amazing discovery, says Nils-Erik Olsson, President of Stockholm amateur astronomers.
Kian Jek and Robert Gagliano, two U.S. amateur astronomers found the planet that is within 5000 light years away and is called PH1 for the international group Planet Hunters, writes the Daily Telegraph. It is believed to be six times as large as Earth.
The planet spins around two stars, which in turn has two other stars orbiting further out, said AFP.
The find is unique.
– It is fascinating to try to imagine what it would be to visit a planet with four suns in its sky, but this new world confuses astronomers. It is not clear how it was shaped in such an environment, says researcher Chris Lintott of Oxford University, the British Daily Telegraph.
A team of professional astronomers have confirmed the find, the newspaper said.
Nils-Erik Olsson, President of Stockholm amateur astronomers, fascinated by discovery.
– It is an amazing discovery. It is harder than finding a needle in a haystack. It is well every amatörastronoms highest goal to find something that no other discovery, he says.
Nils-Erik Olsson explains that you can discover new planets in different ways, but there are two main methods.
Can see the plane pass Star
A planet can for example be detected as it passes a star that is aligned to the earth.
– When it passes in front of the star obscures the a small part of the star’s light, says Nils-Erik Olsson.
– But what passes need not be a planet moves around the star. It can be a star goes out or a plane that does not move around the star or gas cloud that is so dense that it blocks light from the star to us. But when it happens just once, you have to study this several times to confirm that it spins around the star.
When you know that it is a planet revolving around a star using various metrics to find out more about it, as the mass, the distance from the earth is and what speed it has, for example.
A plane can also be detected if the star does not move a bit strange in its path.
– If it moves incorrectly, upside down or sideways, its orbit can sense that there is something. The only thing that can disrupt a star’s path is to a large mass moving around, says Nils-Erik Olsson.
