The largest 10 planets in the universe are: R 136a 1, Shield UY, Cygnus NML, WOHG64, Zephyr 1-26, Sagittarius VX, Cepheus VV, Dog VY, Scorpio AH and Cepheus RW.

1、R 136a 1

Blue giant is a hydrogen-rich blue giant with a radius of 39.2R, its mass is 265,438+05 times that of the sun, and its density is 250 times that of the sun. It is one of the most massive stars at present.

2, shielding UY

UY is a red Supergiant star found in 1860 and one of the top ten stars in the universe. Its radius is 1708 times that of the sun, its volume is 5 billion times that of the sun, and it is 9500 light years away from the earth. It is one of the largest stars known at present, but it is impossible to judge its size at present because there are some opaque gases and dust around it.

3.cygnus

Cygnus NML is a red Supergiant star in Cygnus and a semi-regular variable star with a period of 940 days. It is 5250 light years away from the earth. What is its absolute thermal magnitude? 9.4 is one of the brightest stars at present.

4、WOHG64

WOHG64 is a red Supergiant star located in the Large Magellanic Cloud. Its radius is 2000 times that of the sun, its diameter is 1.540 times that of the sun, and its brightness is 220,000 times that of the sun. It is not only one of the top ten planets in the universe, but also one of the largest stars known at present.

5. Westeru 1-26

Westerloo 1-26, also known as Westerloo 1BKSA, was found in 196 1. It is a red Supergiant star located in the supercluster Westerloo 1, and its radius is 1530 times that of the sun. Is one of the stars that have developed greatly at present.

6. Sagittarius VX

Sagittarius VX is a red Supergiant star and a semi-regular variable star in Sagittarius, with a light change period of 732 days. It is about 5400 light years away from the earth, with a diameter of 1.940 times that of the sun, and its brightness is relatively high. But it is worth mentioning that its density is very low, and its mass is only 1.2 times that of the sun.

7. Cepheus VV

Cepheus VV is an eclipsing binary star, consisting of a red Supergiant star and a blue dwarf. It is 4900 light-years away from the earth and has a radius of about 1050- 1900 r. Although it is large, its density is relatively small and its surface temperature is relatively low.

8.canis major Vi

VY is a red Supergiant star in Canis Canis, 3900 light years away. Its mass is 17 times that of the sun, its radius is 2069 times that of the sun, and its brightness is 300,000 times that of the sun. In addition, it is worth mentioning that VY dogs are rich in oxygen.

9. Scorpio

Scorpio AH is a red Supergiant star of Scorpio and one of the top ten stars in the universe. It is 0/200 light-years away from the earth, and its radius is about 1287- 1535 times that of the sun. It is one of the largest stars known at present. In addition, its best observation time is from July to September every year.

Cepheus RW 10

Cepheus RW is a Supergiant star in Cepheus and one of the top ten planets in the universe. It is about 14000 light years away from the earth, with a long light variation period of about 70 years and a radius of about 1450- 1758R, and it is still in the evolution stage to red Supergiant star.
