The biggest star in the universe is UY Scuti, a red hypergiant in the constellation Scutum. It has an estimated radius of 1,708±192 solar radii, which means that if it were placed at the center of our solar system, its photosphere would extend past the orbit of Jupiter. The volume of UY Scuti is estimated to be 5 billion times that of the sun, which means that you could fit over 5 billion suns inside of it.

It has an estimated radius of 1,708±192 solar radii, which means that if it were placed at the center of our solar system, its photosphere would extend past the orbit of Jupiter. The volume of UY Scuti is estimated to be 5 billion times that of the sun, which means that you could fit over 5 billion suns inside of it.

UY Scuti is a very luminous star, with an absolute magnitude of −8.1. This means that it is 500,000 times brighter than the sun. UY Scuti is also a very variable star, with its brightness fluctuating over time. The star's variability is thought to be caused by pulsations in its atmosphere.

UY Scuti is a very young star, with an estimated age of only 10 million years. This is very young for a star of its size, as most red hypergiants have lifetimes of only a few million years. UY Scuti is expected to end its life in a supernova explosion within the next few million years.

Here are some other facts about UY Scuti:

* It is about 9,500 light-years from Earth.

* It has a mass of about 23 solar masses.

* Its surface temperature is about 3,500 degrees Kelvin.

* It is a member of the Scutum-Centaurus OB association, a group of young stars that are located in the Milky Way galaxy.

UY Scuti is an amazing star, and it is one of the most fascinating objects in the universe. It is a testament to the vastness and diversity of the cosmos that such a massive and powerful star can exist.

about the biggest star in the universe, UY Scuti:

* UY Scuti is a red hypergiant star located in the constellation Scutum.

* It has an estimated radius of 1,708±192 solar radii, which means that if it were placed at the center of our solar system, its outer atmosphere would extend past the orbit of Jupiter.

* The volume of UY Scuti is estimated to be 5 billion times that of the sun, which means that you could fit over 5 billion suns inside of it.

* UY Scuti is a very luminous star, with an estimated luminosity of 340,000 times that of the sun.

* It is also a very variable star, with its brightness fluctuating over time.

* UY Scuti is a very young star, with an estimated age of only a few million years.

* It is expected to end its life in a supernova explosion within the next few million years.

Here are some other interesting facts about UY Scuti:

* Its name comes from the constellation in which it is located, Scutum, and the fact that it is the 18th brightest star in that constellation.

* It is so large that its surface gravity is only about 1/100th of the surface gravity of the sun.

* This means that if you were to stand on the surface of UY Scuti, you would weigh almost nothing.

* UY Scuti is so far away from Earth that it takes its light about 9,500 years to reach us.

* This means that we are seeing UY Scuti as it was 9,500 years ago.

UY Scuti is an incredible star, and it is one of the most fascinating objects in the universe. It is a testament to the power of nature, and it shows us just how vast and amazing the universe truly is.

The biggest star in the universe is UY Scuti, a red hypergiant in the constellation Scutum. It has an estimated radius of 1,708±192 solar radii, which means that if it were placed at the center of our solar system, its photosphere would extend past the orbit of Jupiter. By volume, you could fit over 5 billion suns inside UY Scuti.

UY Scuti is a very unstable star and is expected to go supernova in the near future. When it does, it will be one of the most spectacular events in the universe. The explosion will be so bright that it will be visible during the daytime for several weeks.

Here are some other facts about UY Scuti:

* It is one of the most luminous stars known, with a luminosity of about 340,000 times that of the sun.

* It is one of the coolest hypergiants, with a surface temperature of about 3,000 degrees Kelvin.

* It is one of the most distant stars known, at a distance of about 9,500 light-years from Earth.

UY Scuti is a truly amazing star, and it is a reminder of the vastness and beauty of the universe.

Here are some additional findings about UY Scuti:

* Its mass is estimated to be between 15 and 30 solar masses.

* Its age is estimated to be between 6 and 10 million years.

* It is located in the Scutum-Centaurus Arm of the Milky Way galaxy.

UY Scuti is a very rare star, and there are only a handful of other stars known to be as large. It is a fascinating object, and it continues to be studied by astronomers.
