WASHINGTON (AFP) - Astronomers have spotted the largest yellow star ever observed in our galaxy and 1,300 times larger than the sun.

The yellow hypergiant star HR 5171 A is also in the top-10 of the largest stars known and about one million times brighter than the sun, Mr Olivier Chesneau, whose team made the discovery, said on Wednesday.

Despite its great distance of nearly 12,000 light-years from earth, the object can just about be seen with the naked eye.

"The new observations also showed that this star has a very close binary partner, which was a real surprise," said Mr Chesneau, of the Observatoire de la Cote d'Azur, in Nice, France. "The two stars are so close that they touch and the whole system resembles a gigantic peanut."
