The largest stars, in contrast, will be cool supergiants.
Case in point, VY Canis Majoris is only 3,500 Kelvin, and a really big star would be even cooler.
At 3,000 Kelvin, Humphreys estimates that cool supergiant would be as big as 2,600 times the size of the Sun.
How big is the biggest star compared to Earth?
The video “Star Size Comparison” (duration: 2:34) nicely visualizes how tiny Earth (diameter 12756 km) is compared to the Sun (diameter 1,392,000 km, 109.1 times Earth’s). And how tiny the Sun is compared to other stars. Factoid from the video: VY Canis Majoris (a red hypergiant) is the largest known star.
What is the diameter of the largest star?
VY Canis Majoris. This red hypergiant is among the largest known stars in our galaxy. It has an estimated radius between 1,800 and 2,100 times the radius of the Sun. At this size it would reach nearly to the orbit of Saturn if placed in our solar system.
How big is Uy scuti compared to the Earth?
If it is smaller by 192 solar radii, there are a few other candidates that would beat UY Scuti. The approximate size of the star is about 750m miles, or nearly eight astronomical units, where one astronomical unit is the distance between the earth and the sun.
Is VY Canis Majoris bigger than Uy scuti?
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 big is the biggest black hole?
Astronomers have discovered what may be the most massive black hole ever known in a small galaxy about 250 million light-years from Earth, scientists say. The supermassive black hole has a mass equivalent to 17 billion suns and is located inside the galaxy NGC 1277 in the constellation Perseus.
What is the biggest thing in the universe?
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure.
Is the sun larger than Jupiter?
Jupiter is much larger than Earth and considerably less dense: its volume is that of about 1,321 Earths, but it is only 318 times as massive. Jupiter’s radius is about 1/10 the radius of the Sun, and its mass is 0.001 times the mass of the Sun, so the densities of the two bodies are similar.
How many times bigger is Uy scuti than the sun?
In terms of sheer physical size, the star UY Scuti is considered the biggest known. It’s only 30 times the sun’s mass, but has a radius more than 1,700 greater than the sun.
Who is the biggest star in the world?

What is the size of VY Canis Majoris?
987.89 million km
How did VY Canis Majoris get its name?
The first known recorded observation of VY Canis Majoris is in the star catalogue of the French astronomer Jérôme Lalande, on 7 March 1801, which lists it as a 7th magnitude star. It was given the variable star designation VY Canis Majoris in 1939, the 43rd variable star of the constellation Canis Major.
Is the sun the biggest star in the universe?
The extreme red hypergiant star VY Canis Majoris compared to the Sun and Earth’s orbit.
How many stars are in the Milky Way galaxy?
250 billion ± 150 billion
What is a white hole NASA?
In general relativity, a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black hole, which can only be entered from the outside and from which matter and light cannot escape.
What is the black hole at the center of the Milky Way called?
The complex astronomical radio source Sagittarius A appears to be located almost exactly at the Galactic Center (approx. 18 hrs, −29 deg), and contains an intense compact radio source, Sagittarius A*, which coincides with a supermassive black hole at the center of the Milky Way.
How big is the universe?
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
What is the oldest thing in the universe?
With a redshift of z = 8.2, at the time of observation, the burst was the most distant known object of any kind with a spectroscopic redshift. GRB 090423 was also the oldest known object in the Universe, as the light from the burst took approximately 13 billion years to reach Earth.
What is the largest non gas planet?
In May 2014, previously discovered Kepler-10c was determined to have the mass comparable to Neptune (17 Earth masses). With the radius of 2.35, it is currently the largest known planet likely to have a predominantly rocky composition.
What is bigger than a supercluster?
Superclusters form massive structures of galaxies, called “filaments”, “supercluster complexes”, “walls” or “sheets”, that may span between several hundred million light-years to 10 billion light-years, covering more than 5% of the observable universe. These are the largest known structures to date.

Why is the Pistol Star Blue?
The Pistol Star is a blue hypergiant star; one of the most luminous known in the Milky Way. It is one of many massive young stars in the Quintuplet cluster in the Galactic Center region. The star owes its name to the shape of the Pistol Nebula, which it illuminates.
What is a blue Hypergiant?
A hypergiant (luminosity class 0) is a star with an enormous mass and luminosity, showing signs of a very high rate of mass loss. The exact definition is not yet settled. Hypergiants are the largest stars in the universe, usually larger than supergiants. It is one of the extreme luminous supergiant stars.
