Which planet is the largest in the universe

UY is the largest star in the known universe today. It is 5 billion times the size of the Sun and only 32 times the mass of the Sun. The most massive star known is R136A1, which is about 265 times the mass of the Sun.

If you want to talk about the actual size.

The largest found so far is the Huppard N (Ita).

It is an irregular variable star, with absolute magnitudes ranging from -4 to -12 (horror!). At a distance of 6,500 light-years from Earth, it is estimated to have a mass of 100 times that of the Sun, which is close to the theoretical maximum mass of a star.

If the apparent diameter is the sun and the moon, which have an apparent diameter of 31 arc seconds, and the naked eye can see the circular surface, but no other celestial body can see the circular surface with the naked eye (except for the tail of a comet).

The largest planet in the universe is the red supergiant, which is more than 100 to 1,000 times the diameter of the Sun. The diameter of the Sun is about 1.4 million kilometers, which can fit 110 Earths. How huge a red supergiant that can rank thousands of Earths in its own diameter is truly worthy of being the champion of planet size.

First of all, your so-called "total imperial constellation of the Tianlang Galaxy" does not exist at all; Second, you are grossly underestimating the difference in the volume of the stars from one another. There are countless stars hundreds of times larger than the Sun.

Regarding the landlord's question, the universe is very large, and it is difficult to say which one is the largest, and it will never be possible to come to this conclusion. But I can tell you which type of star is the largest. That's a red giant.

This is the state in which the star evolves to its later years. These stars are characterized by low surface temperatures and extremely large volumes, but relatively low density. For example, the Antares of Scorpio.

2. The Great Horn in the constellation of Shepherd and Betelgeuse in the constellation Orion are both red giants.

O Earth!! Do you think that you can see other planets in their entirety in your eyes, but have you seen the earth in their entirety?

The earth occupies half of the heavens and the earth - half of the sky.

If it's the solar system, it's Jupiter, hee-hee, and the universe is so big that I don't think anybody will know about it

It is the star of the constellation Cepheus or Betelgeuse or Tianjin four.

In the solar system, Jupiter is the largest.

As far as our solar system is concerned, the largest is Saturn.

Your eyeballs are so big that the universe is so big, and the biggest so far is not necessarily the largest in the universe, although I don't know which one is the largest

Nobody knows.

Because today's most advanced binoculars can't see the entire universe.

Perhaps human beings have not yet been able to see the universe, and they may not know until a billion years later.

I think you are asking a question that even scientists don't know about!
