Top ten rankings of the largest planets in the universe

The largest planet (mass) in the universe is ranked as follows:

1、R 136a 1

2, shielding UY

3, Cygnus NML planet

4. Westeru 1-26

5. Cepheus VV

6, Orion planet

7, Gemini beta star

8.canis major Vi

9. Sagittarius VX

10、WOHG64

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. It is estimated that its mass is as high as 265 times that of the sun and its diameter is about 30 times that of the sun. UY is a star with its own nuclear reaction, which will emit light and heat. Cygnus NML is the largest known star in the universe, and it emits more radio than the sun 1650 times.

WOHG64 is a red Supergiant star located in the barley (Zhelun) cloud galaxy, roughly estimated to be 654.38+0.6 million light years away from the Milky Way. Its radius is about 65,438+0,540 suns. WOHG64 is at the end of planetary evolution, and has ejected one tenth of the total mass. These substances and dust are around WOHG64 and have a thickness of one light year. A supernova explosion is expected to occur after 2000.

Brief introduction of solar system

The solar system is a celestial system centered on the sun and bound by its gravity, including the sun, planets and their satellites, dwarf planets, asteroids, comets and interplanetary matter. The solar system is located about 24,000 ~ 27,000 light years away from the center of the Milky Way (the number of stars in the Milky Way is about 654.38+00 billion ~ 400 billion, and the sun is just one of them). The sun orbits the galactic center at a speed of 220 kilometers per second, once every 250 million years. The direction of the sun's movement is basically towards Vega, close to Ursa major.

The formation of the solar system began with the gravitational collapse of a huge interstellar molecular cloud about 4.6 billion years ago. Most of the mass in the solar system is concentrated on the sun, and Jupiter is the largest of the existing celestial bodies. Eight planets revolve counterclockwise around the sun, and there are also smaller celestial bodies located in the asteroid belt between Jupiter and Mars. There are also a large number of small celestial bodies in the Kuiper Belt and Oort Cloud, and there are many satellites orbiting planets or small celestial bodies. Every planet outside the asteroid belt has a planetary ring.
