Opened biggest star

Its diameter exceeds the corresponding figure of our star 1.3 thousand times the brightness 1 million times

Astronomers from France in the constellation of Centaurus saw one of the largest stars in the Universe belonging to the class of yellow hypergiants. At this point the star is called HR 5171A, it is removed from the Earth is 12 thousand light years.

Instruments of the VLT telescope helped astronomers to estimate the size and other parameters of the giant star HR 5171 A in the constellation of Centaurus, whose brightness is about a million times higher than that of our Sun, and find her “secretive” companion, said in the journal Astronomy & Astrophysics.

“Observations of HR 5171 A has shown that this world is a neighbor, orbiting around it in close orbit, which is extremely surprised us. These stars are located to each other so close that they touch each other, and the whole system resembles a gigantic peanut walnut. This star-companion is interesting for us from the point of view that it could potentially “strip” the outer shell of a giant and thereby change the course of its evolution,” said Olivier Honestly from the Observatory of the côte d’azur (France).
