How big is UY Scuti compared to the sun?
How big is UY Scuti compared to the sun?
So while UY Scuti is only around 30 times more massive than the sun, it has a radius somewhere in the region of 1,700 times larger than the radius of the sun. This star is one of a class of stars that varies in brightness because it varies in size, so this number is also likely to change over time.
Is the UY Scuti hotter than the sun?
UY Scuti is releasing much more heat energy than the sun, but its surface is cooler. It’s kind of like the difference between a candle an an electric blanket.
What if UY Scuti was our Sun?
It’s a pulsating star that swells and shrinks periodically, usually shining about 400,000 times brighter than our Sun. If UY Scuti took our Sun’s place at the center of our solar system, it would engulf everything as far out as the orbit of Saturn.
How many suns fit in Betelgeuse?
The star is approximately 548 light-years from Earth. Betelgeuse is a red supergiant star roughly 764 times as large as the Sun. For comparison, the diameter of Mars’s orbit around the Sun is 328 times the Sun’s diameter.
Which is the heaviest star?
That honor goes to R136a1, which weighs in at about 300 times the mass of the sun but only about 30 solar radii.
Which star is bigger than Sun?
Sirius, Pollux, Alpha Centauri A, UY Scuti etc. are some examples of stars bigger than the sun.
What is world’s 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 is the largest Sun?
Stephenson 2-18 is a red supergiant. The largest star in the known universe is called Stephenson 2-18, a star that has a radius 2,150 times that of the sun. That is 930,000,000 miles in size or roughly 10 billion times the volume of the Sun.
Is a star hotter than lava?
A red dwarf star, the coolest of the stars that can fuse hydrogen, sits at about 3000 C. Lava usually checks in at a temperature somewhere between 700 degrees and 1200 degrees. At its hottest, lava is only half the temperature of the surface of the dimmest stars.
Which is the biggest thing in 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.
What old is the Sun?
Our Sun is 4,500,000,000 years old. That’s a lot of zeroes. That’s four and a half billion.
How old old is the universe?
76 line illus. Astronomers have determined that our universe is 13.7 billion years old.
Can 1000 Earths fit in the Sun?
So, how many Earths can fit in the Sun? The answer is that it would take 1.3 million Earths to fill up the Sun. That’s a lot of Earths. The Sun makes up 99.86% of the mass of the Solar System.
How many galaxies are there?
The Hubble Deep Field, an extremely long exposure of a relatively empty part of the sky, provided evidence that there are about 125 billion (1.25×1011) galaxies in the observable universe.
What type of galaxy is the Milky Way?
The Milky Way is a huge collection of stars, dust and gas. It’s called a spiral galaxy because if you could view it from the top or bottom, it would look like a spinning pinwheel. The Sun is located on one of the spiral arms, about 25,000 light-years away from the center of the galaxy.
What is the biggest galaxy?
Earlier this year, astronomers found an absolute monster of a galaxy. Lurking some 3 billion light-years away, Alcyoneus is a giant radio galaxy reaching 5 megaparsecs into space. That’s 16.3 million light-years long, and it constitutes the largest known structure of galactic origin.

The largest black hole ever found in the known universe is found in Ton 618. This is a hyper luminous Lyman-alpha blob that has a black hole that measures 6.6×1010 solar masses. It has a mass that equals about 66 billion times that of the Sun. This supermassive black hole is some 18.2 billion light-years from Earth.
