What is the name of the hottest star?
The hottest known star, WR 102, is one such Wolf-Rayet, sporting a surface temperature more than 35 times hotter than the Sun. Like Baskin-Robbins, Wolf-Rayet stars come in a variety of flavors.
What if Sirius replaced our Sun?
Sirius is twice as large as our sun, and 20 times brighter. If it were positioned in place of our sun, certainly our atmosphere would be stripped away, maybe evaporate the oceans, and the enormous radiation would fry most living things. Thereof, will we see scuti supernova? Yes, but not as you expected. UY Scuti and VY Canis Majoris has Apparent magnitude about -8 at distance of 4ly, and yes, you will see them with naked eye in daytime.
Also, what would happen if earth was as big as the sun?
If our world was as big as the Sun, then, like the water, our soil would have to be spread out to cover a much larger space. Less soil would mean less food, while the demand for food would stay the same. Also, what is the biggest thing in the universe? The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure.
Who found UY Scuti?
German astronomers UY Scuti was discovered by German astronomers at the Bonn Observatory in 1860. However, the star was better documented in 2012 with the help of greater technological equipment. Data revealed that UY Scuti was around 7 to 10 times more massive than our Sun, and had a radius approximately 1.700 times larger. One may also ask is uy scuti bigger than betelgeuse? If you think Betelgeuse is large, it does not even compare to the largest star we have located. The largest star we have identified is UY Scuti, which was found in 2012. Its radius is in between 1,054,378,000 and 1,321,450,000 miles, which is about 1700 times larger than the radius of Sun.
