Nebulas or vast clouds of gas also have.

1 708 192 solar radii the biggest known star in the universe with a radius of 1 708 192 solar radii uy scuti is probably the biggest known star. The sun appears so large compared to the other stars because it is so much closer to us than any other star. It is first cataloged in 1860 by german astronomers at the bonn observatory. The biggest known galaxy is ic 1101 which is 50 times the milky way s size and about 2 000 times more massive.

The sun is just an average sized star. It is about 5 5 million light years across. The uy scuti is a variable star which means that the star is closer to the milky way. ε aurigae was incorrectly claimed in 1970 as the largest star with a size between 2 000 r and 3 000 r even though it later turned out not to be an infrared light star but rather a dusk torus surrounding the system.

As a result astronomers estimate that its size could be anywhere from 1 642 to 2 775 solar radii which means it could either be the largest star in the known universe with a margin of 1000. Mu cephi about 1500 times the size of our sun. The most massive star in the universe is in fact not the sun it is called uy scuti which is a hypergiant located in the constellation scutum. For example below is a list of some of the largest stars in our galaxy and how they compare to our sun.
