One of the peculiarities stars, is that it is not usually born by themselves. They usually do it with another similar star (or even more), forming at the same time similar compounds.
Moreover, as the Spanish newspaper ABC reported, about 85% of them spend their lives with their "brothers", remaining united in gravity.
However, within the stars of our galaxy that is not next to his brother, it is precisely that ground of the solar system. This, despite the fact that experts believe it was born 4.500 million years ago.
In fact, astronomers claim that our star lived in a binary system with one of his comrades, but that a cosmic event made them separate.
That is why different researchers believe that somewhere they have lost the twin brother of the Sun, which could eventually have been discovered.
According to the Science Alert portal, a team of astronomers led by researchers from the Institute of Astrophysics and Space Sciences in Portugal, Astronomy and astrophysics noted that this star, called HD 186302, is 184 light years from Earth.
Although there is no way to check 100% "kinship", experts say that HD 186302 has a temperature, glow and chemistry quite similar to that of Sun. As if this was not enough, they are practically the same age.
These features far outweigh those of the star type F HD162826, which was proposed as Sun's sister in 2014.
All these similarities between Sun and HD 186302 mean that even if they do not have a direct relationship, their finding is extremely important.
And her simple presence raises interesting questions: will they have planets that are spinning around her? And if it existed, could it have habitats?
