According to AFP, the newly discovered star called HR 5171 A, located far from Earth about 12,000 light years.
Diameter of HR 5171 A is greater than 1.300 times and brighter than the Sun about a million times. Compared with Betelgeuse, one of the biggest and brightest stars is known by astronomers, HR 5171 A is larger than 50%. With this size, the astronomers said this is the largest gold star that is ever observed in the galaxy.
HR 5171 A is part of a binary star system and located very close to the other star, forming a binary system structure shaped like a giant peanut.
The research team from the European Southern Observatory (ESO) said the giant gold star is a rare type of star in the galaxy. So far, experts discovered 12 new stars of this type.
