WASHINGTON (Reuters) -In an unforgettable image of the movie “Star Wars” in 1977, the young hero Luke Sky Walker stares on the sun on the horizon on his desert planet Tatwin. Astronomers have since discovered worlds, called circular planets, which revolves around two stars.
But for the absolute exotic, it will be difficult to lead a newly described fraudulent planet located in a relatively nearby place in the Milky Way galaxies. It does not revolve around two stars, but a structure of brown – very small heavenly beings so that they are not a star and too big so that they cannot be a planet. Its orbit is not different from any other registered planet.
Brown dwarves can be considered stars wishing, during their formative stages that did not reach the necessary mass to ignite nuclear fusion in its heart like the star. But it is more large than the largest planets and is modestly ill.
Using a very large telescope in Chile, the researchers found evidence of the presence of a planet about 120 light years – perhaps a gas planet at least four or five times the mass of the Earth – revolves around two brown dwarfs, each about 35 times more huge than Jupiter. The optical year is the light distance per year, 5.9 trillion mile (9.5 trillion km). Jupiter is the largest planet in our solar system.
The brown dwarfs are binding and orbit near each other – the closest of approximately 4 % of the distance between the Earth and the sun. The planet, named 2M1510 (AB) B, revolves around this pair. Another brown dwarf is in this system, but it is very far – about 250 times the distance between the Earth and the sun – to pull it out of the other than to disturb the other two.
Among the approximately 5,800 planets outside our solar system – called Exoplanets – have been confirmed so far, only 16 are a circle. Until now, none of these have been found around brown dwarves, instead of regular stars.
The nature of the orbit of this planet is also unique. Instead of following the plane created in the orbit of the brown dwarves, the planet is almost perpendicular to the plane – called the polar orbit – on a flight of at least 100 days.
“The satellite throughout a polar course around the Earth is the one that passes over the Arctic and South Pole. Thus, it will be in the course of 90 degrees to the axis of rotation in the Earth,” said Thomas Baycruvte, a doctorate in astronomy at the University of Birmingham in England and the author of the study that was published in the magazine of science in the magazine.
There is no planet in our solar system with a polar orbit. Many external planets known to follow up on such orbit are only one star path.
When two stars, or in this case, two brown dwarfs revolve, they rotate each other, they are called a bilateral system, such as fictional output in the “Star Wars”. However, the observer view of this planet will be the opposite of the opinion that Luke Sky Walker saw.
“This will be different from the image of Tatooine. Both brown dwarfs will be identical and red. Since they are brown dwarves, they are faint from the sun in general, although the extent of their appearance in the sky also depends on the extent of its proximity to the planet.”
These binary dwarves have a mass of about 4 % of the sun and only about 0.1 % of illuminating.
“This looks like a strange formation of a planetary system. It may be the most important discovery because the first outdoor planets are the diversity of planetary systems. It seems to challenge our expectations, which is great – they offer a great opportunity to learn.”
Trioid said that while scientists have previously assumed the presence of a planet outside the planets in a polar orbit around a binary system, this is the first good evidence for this.
