What is known as the largest star in the universe?

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 is the largest star in the Universe 2022?

If placed at the center of the Solar System, its photosphere would engulf the orbit of Saturn.” Surpassing UY Scuti, St2-18 is now considered to be the largest star in the known universe.

What star is bigger than UY Scuti?

The upper part of the range would make it larger than UY Scuti. Another hypergiant star is WOH G64, also in the Large Magellanic Cloud, and thus located at a distance of some 168,000 light years from Earth.

Is UY Scuti or Stephenson 2 18 bigger?

Stephenson 2-18 compared with UY Scuti

WOH G64 has an estimated radius between 1,540 and 1,730 solar radii, which is considerably smaller than both St2-18 and the current runner-up, MY Cephei (2,061 R).
