What is the largest star in all of space?
UY Scuti
The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.

What are the 3 largest stars?
The three biggest stars are KW Sagitarii (distance 9,800 light-years), V354 Cephei (distance 9,000 light-years), and KY Cygni (distance 5,200 light-years), all with radii about 1500 times that of the Sun, or about 7 astronomical units (AU).
What if UY Scuti exploded?
So the force of 100 stars exploding would obliterate everything nearby. Even if Earth was far enough away to survive the blast, without the star, there would be no heat and no light, and life could not survive on Earth without them.
Is UY Scuti bigger than the Milky Way?
This discovery was quite overwhelming, and for a period of time UY Scuti held the title of the biggest known star in the Milky Way. Its size surpassed previous records held by other large stars such as Betelgeuse, VY Canis Major, and NML Cygni.
Did UY Scuti go supernova?
Because of this pulsation, its exact size also varies, making an exact estimation difficult. The temperature on UY Scuti is estimated to be around 3,365 K. It is believed that UY Scuti has begun to fuse helium and will eventually go supernova.
