What is the largest type of star called?
The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy.

Is Stephenson 2/18 A hypergiant star?
Stephenson 2-18 (St2-18), also known as Stephenson 2 DFK 1 or RSGC2-18, is possibly a red supergiant or red hypergiant star in the constellation of Scutum, although some sources consider it to be a foreground object.
Is UY Scuti shrinking?
Size, and Mass UY Scuti’s exact size is difficult to determine due to its pulsation. However, recent estimates in 2019 have made the planet a bit smaller due to its change in temperature. The radius has dropped – it now has 1708 times the radius of our Sun.
Will UY Scuti go Hypernova?
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.

Is quasi star bigger than UY Scuti?
Quasi-Star vs UY Scuti The largest star that we know of is UY Scuti, whose estimate as mentioned earlier 1,708 times that of the Sun. A theoretical Quasi-Star would be much larger. The straight to the point answer would be Yes, a Quasi Star is bigger than UY Scuti.
What is the biggest star compared to the Sun?
The largest star in the observable universe, VY Canis Majoris, compared to our Sun: It’s diameter is around 2000 times the diameter of our Sun. Take another look. See that tiny dot on the bottom left, that’s our Sun.
What is the biggest known star in the universe?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it’s not alone in dwarfing Earth’s dominant star.
How large is the biggest star?
The largest known star is VY Canis Majoris. It’s a red hypergiant in the constellation Canis Major . University of Minnesota Professor Roberta M. Humphreys originally estimated the radius of VY CMa at 1,800 to 2,100 solar radii; which is about 1,975,000,000 kilometers or 1.227 x 10^9 miles in diameter.
What was the biggest star ever discovered?
W26 is about 1,500 times wider than the sun, making it the biggest known star in the universe. The red supergiant star is nearing the end of its life and will eventually explode as a supernova, researchers said.
