What is the largest planet in the universe so far? Except for black holes

Antares is not the biggest. Having said all this upstairs, the largest planet so far is the star VY Canis Major, which is about 2,200 times the diameter of the Sun, about 80 to 10 billion times the volume of the Sun, and nearly 100 times the mass of the Sun. If it were placed in its current position in the solar system, its edge would go straight to the orbit of Uranus.

Although it is only 5,000 light-years away, we can't see it with the naked eye because of the interstellar clouds. VY Canis Major is a red supergiant on the verge of death.

There is also the most massive star, R136A1, which is now 265 times the mass of the Sun, but it is in the main-sequence stage, and its volume is only hundreds of thousands of times that of the Sun, and when it enters the red supergiant stage, it may be larger than VY Canis Major, but this is millions of years away.

Black holes don't have a concept of volume, just say what it's equivalent to, there is no concept of time and space there is the extreme of gravity but it seems to have mass! Criticism and correction are welcome if the understanding is superficial.

Black holes are not necessarily the biggest! Black holes have a lot of mass! Some of them are not as big as the earth!

The largest planet discovered by mankind at the moment.

VY Canis Major, a red supergiant located in the constellation Canis Major, is located 5,000 light-years from Earth.

Its mass is about 30 40 times the mass of the Sun, and its diameter is about 1800 2100 times the radius of the Sun.

Canis Major VY is not only huge, but also 500,000 times more luminous than the Sun.

Canis Major is at the end of the stage of stellar evolution and is spewing out a large amount of gas at a massive rate. In the future, it may trigger a supernova**.

Added: It has a diameter of 2,800,000,000 km if you take 900 km h an airplane to fly a circle on the surface (diameter 900 24 365 x compass).

Then you need to use 1100 years.

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.

In the universe, the largest.

The planet is a red supergiant, which is more than 100 times to more than 1,000 times the diameter of the Sun.

The four largest red supergiants in the Milky Way are the constellation Coffus, Sagittarius KW, V354 Cactus and Cygnus KY

As for which one is the largest, I think with the progress of science and technology, the exploration of the universe continues to deepen, only bigger, not the largest.
