Astrologists announced on Wednesday that they had discovered a huge planet that revolves around a small star, a strange pair that led to the stumbling of scientists.
Most of the stars via the Milky Way are small red dwarves like TO6894, which have only 20 % of our sun mass.
It was not possible for such weak and weak stars the conditions needed to form and host huge planets.
But an international team of astronomers discovered the unambiguous signature of a giant gas planet revolving around TO6894, According to the study In the Journal of Astronomy. This makes the star the smallest star known for hosting a giant gas.
The planet has a slightly larger radius than Saturn, but only half of its mass. His star revolves in a little more than three days.

Astronomers have discovered the planet when searching through more than 91,000 low -mass dwarves that NASA noted Telescope space. Then its existence was confirmed through earthly telescopes, including Chile Very large telescope.
“The fact that this star hosts a giant planet that has great effects on the total number of giant planets that we appreciate in our galaxy,” the author, the author, Daniel Piles of Warwick University in the United Kingdom He said in a statement.
Another participant author, Vincent Van Eilen, of the University of London College, said he was “an interesting discovery.”
“We don’t really understand how a small star star can form such a huge planet!” He said. “This is one of the goals of searching for more external planets. By finding planetary systems that differ from our solar system, we can test our models and better understand how our solar energy system is formed.”
The planet is unusually cold
The most prominent theory of how to form the shape of planets is called basic accumulation.
The process begins when it is called a gas and dust loop – the protoplantine disk – which surrounds a newly formed star in the heart of a planet. This nucleus attracts more gas that is an atmosphere, and in the end the snow falls into a gas giant.
Under this theory, it is difficult for low -mass stars to host giant planets because there is not enough gas and dust to start building an essence in the first place.
A competitive theory suggests that these planets are formed instead when their protoplantic tablet becomes unstable in terms of gravity and separates, with the formation of collapsed gas and dust.
The researchers said it does not seem to be the theory explaining the existence of the newly discovered planet to-6894b.
The planet also raises scientists because it is strange in a strange way.
Most of the discovered gas giants outside our solar system so far were what is known as the name “Hot Jobsters,” The temperatures rise more than 1000 ° C. The researchers said that the newly discovered planet seems less than 150 ° C.
“The temperatures are sufficiently low so that the notes in the ammonia atmosphere can show us, which will be the first time that it is located in an atmosphere abroad,” said Amaury Trious, co -author of the University of Birmingham.
the James Web telescope for space Its strong view of the planet is scheduled to turn in the next year, which may help discover some of the secrets of this strange planet.
Recent cosmic discoveries
The discovery of the giant planet that revolves around the latest lower star in a series of modern heavenly discoveries is.
Last month, the United States, the “ninth planet”, said that they said that they instead found that it was a. A new dwarf planet In the external access of the solar system. The 2017 new object is called about 430 miles, according to the pre -printing study, making it three times smaller than Pluto.
Also in May, an international team reported that a A newly found heavenly body Perhaps a star, a pair of stars, or anything else-is emitted by X-rays at the same time as you photograph radio waves.
Meanwhile, scientists recently announced that a new offer for the clients around the Milky Way helped them Open one of the many secrets of the solar system. Experts at the American Museum of Natural History in New York were lining up a scene around the Ort cloud that exceeds Pluto. Scientists have never hinted this area, but when the museum experts recorded their scene on the Dome of the Heavenly Dome, which was created using simulation data, they saw a spiral shape.
Scientists have long thought that the Ort cloud was in the form of a ball or a flat shell, distorted from paying and withdrawing other planets and the method of the Milky Way itself. Procitarium hinted that a more complex shape can lie inside.
