The ten largest stars in the universe
1, shield UY, the volume is 5 billion times that of the sun.
2.R 136a 1 is the second largest hydrogen-rich star, and its mass is 2 15 times that of the sun.
3. Cygnus NML is a red Supergiant star and one of the top ten stars in the universe. It is rich in oxygen, but its radius and mass are still unclear because of the dust and some opaque substances around it.
4. Cygnus KY is located in the red Supergiant star of Cygnus, its mass is 25 times that of the sun and its brightness is 300,000 times that of the sun. It is also one of the brightest stars known at present.
Cepheid IV, also known as Pomegranate Star, is a red Supergiant star in Cepheus, which is famous for its red color. Its brightness is 3.43-5. 10, and its luminosity is 350,000 times that of the sun. It is one of the brightest stars known at present.
6. Unicorn V838 is a red Supergiant star among unicorns, and its diameter is about 5-700 times that of the sun.
7.WOH G64 is a red Supergiant star located in the Large Magellanic Galaxy, with a diameter of about 1540 times and a mass of 40 times that of the sun. It is also one of the largest stars known at present.
8.KW Sagittarius is a red Supergiant star located in Sagittarius, with a radius of 1460 times that of the sun. It is one of the top ten stars in the universe. Due to lack of information, its distance from the sun is uncertain.
9. Cepheus V354 is a red Supergiant star located in Cepheus, and its radius is about 1520 times that of the sun. Because it is surrounded by dust, it is generally invisible to the naked eye. In addition, it is worth mentioning that Cepheus V354 may have a supernova explosion in the future.
10. Betelgeuse, also known as Orion α, is a red Supergiant star and one of the top ten Supergiant star in the universe. Its radius is about 1 180 times that of the sun, and it is also one of the largest stars visible to the naked eye. In addition, Betelgeuse may evolve into a supernova in the future.
NASA is about to embark on an ambitious mission to study stars with balloons the size of a football field.
