The ten largest planets in the universe

The ten most massive planets in the universe are R 136a 1, Cygnus NML, Shield UY, Zephyr 1-26, Cepheus VV, Orion, Gemini β, Dog VY, VX Sagittarius and WOHG64.

So far, the most massive star discovered by human beings in the universe is R 136a 1, which is a blue Supergiant star located in the Tarantula Nebula of the Large Magellanic Galaxy. R 136a 1 belongs to Wolf-Rayet stars, and its mass is estimated to be as high as 265 times that of the sun. However, its diameter is about 30 times that of the sun, and it is not the largest star in the universe. In addition, R 136a 1 is the brightest star in the universe, and its brightness is about 8.7 million times that of the sun.

1960, a group of astronomers working in Pretoria Observatory measured the brightness and bright star spectrum of large magellanic cloud. Among them, there is a bright celestial body in the Tarantula Nebula, and the catalog number is R 136. Subsequent observations show that the celestial body R 136 is located in the center of the Tarantula Nebula near a bright area, which is a central area where the formation of giant stars is directly observed.

Star introduction

Stars are giant spheres composed of luminous plasma, mainly composed of hydrogen, helium and trace heavy elements. On a sunny night, there are always countless light spots embedded in the night. Except for a few planets, most of them are stars. The sun is the closest star to the earth, and almost all the stars that can be seen at night are in the Milky Way. The Milky Way has about 300 billion stars, and humans can only observe a small part.

Humans have been observing stars for a long time, and there are various observation methods. Those brighter stars are divided into constellations and clusters, and some stars have their own names. The brightness of a star is called magnitude, and the brighter the star, the lower the magnitude. Astronomers have also compiled a catalogue to facilitate research. Stars will carry out nuclear fusion at the core to generate energy and transmit it to the outside, and then radiate from the surface to outer space. Once the core nuclear reaction is exhausted, the life of the star will come to an end, and at the end of life, the star will also contain degenerate matter.
