The universe is full of unsolved mysteries. Scientists work hard to reveal the secrets. A team of international scientists from the Observatoire de la Cote d¡¯Azur in Nice, France, recently spotted the largest star in our galaxy.

The team discovered the star using the Very Large Telescope (VLT) in the European Southern Observatory (ESO). The newly discovered star is called ¡°HR 5171.¡± It lies about 11,700 light-years away from our planet.

Despite the considerable distance, people can see ¡°HR 5171¡± with their naked eyes. How is it possible? This is because the star is 1,300 times bigger than the sun. Also, it is a yellow hypergiant, which is extremely luminous. It is 1,000,000 times brighter than the sun.

What is more surprising is that there are two stars! The star is a binary system, which means that there are two stars that orbit around each other. The two stars are located so close to each other that they look like a giant peanut. The companion star, called ¡°HR 5171 B,¡± orbits around ¡°HR 5171 A.¡± It takes about 1,300 days to finish its revolution.
