Star size ranking

Star size ranking: shield plate UY, Cepheus IV, WOHG64, Cepheus V354, Cygnus.

1, shielding plate UY: a red giant located in the shielding plate, with a radius of 1708 times that of the sun and a volume of 4.5 billion times that of the sun. It is the largest star known to man. It ranks first among the top ten stars in the Milky Way, about 65.438+0.2 billion kilometers away from the Earth.

2. Cepheus IV: also known as Cepheus μ, located in Cepheus, is a red giant with a radius of 1650 times that of the sun. It looks like a garnet, so it is also called the pomegranate star.

3.WOHG64: The swordfish constellation in Magellanic galaxy is a red giant with a radius of 1540 times that of the sun. This star is the oldest of the eight stars in the Milky Way. At present, it is at the end of the evolution of stars, and it is expected that a supernova explosion will occur after 2000.

4. Cepheus V354: Located in Cepheus, it is a red giant with a radius of 1520 times that of the sun and 9000 light years away from the earth. In addition, Cepheus V354 is at the end of evolution, which may lead to supernova explosion in the future.

5. CygnusKY: A super red giant located in Cygnus, 5,000 light years away from the Earth, with brightness 300,000 times that of the sun and mass 25 times that of the sun. The size of this star is controversial. The radius of Cygnus is 1420-2850 times that of the sun.
