The position of the sun in the solar system is unshakable. It is not only the core of the earth, but also a well deserved cell phone. A steady stream of light and heat supply the growth of all things on earth. Because of its existence, the earth can be prosperous. In front of the sun, all the other celestial bodies in the solar system are brothers, only the sun has played its role to the extreme.

As the first of the eight planets, Jupiter is only 1 / 1300 of the sun. If the sun is compared with the earth, it is estimated that it can hold 1.3 million earths, which is beyond imagination. In the observable field of the universe, there are more than 100 billion stars. In the face of such a large number, can the sun still be on the table? Obviously No. In such a large galaxy, the sun can’t be more ordinary. Among all the stars, which is the largest?

For a long time in the past, astronomers generally believed that uy is the largest star. After many years, according to the latest observation data, a star pulled uy from the largest throne directly. Originally, VX and NML of Cygnus were candidates. Only after its appearance did astronomers completely change their cognition. It was Stephenson 2-18. Another behemoth appears, crushing the shield uy, which can hold 10 billion suns!

According to the data, its diameter is about 2150 times that of the sun, which is beyond recognition. Such a huge area can hold 10 billion suns, and its volume can directly crush the scutellus uy. As long as it exists, other stars are small, which is difficult to compare with. Its edge is 100 million kilometers more than Saturn’s radius, which is amazing. It is understood that it is 20000 light-years away from us. It is the largest star in history. It is extremely large and can last up to 20 million years. Compared with the sun, it is far inferior.

Although its volume is huge, it has lost a lot of life, which is far less than that of the sun. In fact, the rule of the universe is that the larger the volume is, the more fuel will be consumed at the same time. The huge internal radiation pressure can not replenish the fuel, and the life will be shortened. Scientists speculate that in a few million years, Stephenson 2-18 will disappear due to the depletion of fuel, and may trigger a supernova explosion, illuminating the entire galaxy and eventually becoming a black hole or neutron star.

What we need to note is that Stephenson 2-18 is the largest known star, which does not mean that there is no star larger than it. Maybe some day in the future, astronomers will find a star larger than it. The universe is so vast that there are so many stars everywhere. Shield uy has been defeated by its size. It can be seen that there are many secrets hidden in the universe that people don’t know. Let’s leave it to time. Exploring the universe is a long and complicated journey. If you want to be quick, you can’t accomplish such a huge project in a short time. What other stars in the universe do you think are very big? You can leave a message for interaction.
