What universe is the biggest star in?
With that said, so far, the winner of largest star in the known universe probably goes to UY Scuti — a massive red supergiant located in our own Milky Way galaxy in the constellation Scutum and measures about 750 million miles, or nearly eight astronomical units.
What is the 3rd largest star?
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).
Which star is bigger than Sun?
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.
Who is the smallest star?
In 2017, an international team of astronomers announced the discovery of a so-called red dwarf star that's so small it barely functions as a star. Code-named EBLM J0555-57Ab and lying some 600 light-years away, it's similar in size to the planet Saturn.
What is the closest star to Earth?
Proxima Centauri Distance Information Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away. (Or about 268,770 AU.) When we talk about the distances to the stars, we no longer use the AU, or Astronomical Unit; commonly, the light year is used.
Is quasi star bigger than UY Scuti?
The straight to the point answer would be Yes, a Quasi Star is bigger than UY Scuti. A challenger to the title of largest star is Stephenson 2-18 also in the constellation of Scutum the Shield. According to Wiki, the size is 2,149.58 times the size of the Sun based on a Stefan-Boltzmann Law calculation.
