WASHINGTON: Young hero Luke Sky Walker looked at two suns above the horizon on his desert planet, in a memorable picture of the 1977 movie “Star War”.
Astronomers have really discovered the world since then, called the Circle Planet, revolve around two stars.
But it will be difficult to upset a newly described Serbian planet in our Akashiganga galaxy, a relatively near -nearly near -end, in our skying galaxy. It does not go to the two stars but two brown dwarves. And its orbit is unlike any other planet in the record.
Brown dwarfs can be considered a wide -ranging stars that during their early stages, like their stars, the nuclear fusion did not reach the masses. But they are larger than the largest planets and are modest luminous.
Using a very large telescope based on the European Southern Observatory, researchers have found evidence of a planet about 120 120 light years away – perhaps a gas planet crosses the Earth’s large -scale four or five times – two brown dwarfs, 35 times more than each Jupiter. A light year distance travels in one year, 5.9 trillion miles (9.5 trillion kilometers). Jupiter is the largest planet in our solar system.
Two brown dwarfs are bound in terms of gravity and orbit each other – only 4 % closer to the distance between the earth and the sun. The planet, called 2M1510 (AB) B, is orbit around the pair. There is another brown dwarf in this system, but far away – about 250 times between the earth and the sun – to distract the other two to pull its gravity.
Of our solar systems, about 5,800 planets – called Explinates – to date, only 16 are Circles. And so far, none of them were found to have a revolutionary dwarf instead of regular stars.
The nature of the orbit of this planet is also unique. Instead of following a plane set up for a two -brown dwarf orbit, the planet almost stands by the plane – called polar orbit – on a journey that lasts at least 100 days.
“A satellite on the polar orbit around the Earth,” said Thomas Bakrafta, a doctorate student at Birmingham University in England, which will pass through the pole north and the south pole. So it will be on a orbit that will be on the Earth’s rotation axis at 90 degrees, and a felony at the universe. Guide the author of this study published in the Journal of Science Purms.
Our solar system does not have polar orbit in any planet. Such a path is known to follow only one star in orbit.
When two stars, or two brown dwarves in this case, rotate each other, it is called binary system, such as imaginary one in “Star Wars”. However, the theory of an observer on this planet would be the opposite that Luke Sky Walker saw.
“It will be different from the icon of the tattoine. Both brown dwarves will be the same and red, because they are brown dwarves, they are usually unconscious from the sun, though how bright they appear in the sky, it depends on how close the planet is close to them.”
These binary brown dwarves are about 4 % mass of the sun in each and they are only as 0.1 % luminous.
“It appears like a foreign order for the planet system. Perhaps the most important discovery since the first Explanation is how different the planetary systems are. They deny our expectations, which is great – they offer a great opportunity to learn.”
Although scientists had previously speculated the existence of explanations in the polar orbit around the binary system, this is the first good evidence.
