How big can a supergiant star get?
Supergiant stars can have masses from 10 to 70 times greater than our Sun, and when it comes to brightness, some of them can be from 30,000 times or brighter than our Sun. In regards to their radius, supergiants vary greatly, from 30 to 500, or even exceeding 1,000 solar radii.
What is a supergiant?
Supergiants can also be defined as a specific phase in the evolutionary history of certain stars.
What are the largest supergiants ever discovered?
Among the largest supergiants ever discovered are VV Cephei, V354 Cephei, KW Sagitarii, KY Cygni, and the Garnet Star. Supergiant stars come in two flavors, red and blue. Blue supergiants are usually the hottest stars in the universe. Supergiant stars burn very quickly through their hydrogen supplies, thus the reason why they have short lifespans.
How bright is a blue blue supergiant?
Blue supergiants are also quite bright, being between 10,000 to 1 million times brighter than our Sun. They have masses of around 20 to 1,000 times that of our Sun and live very short lives, about 10 million years or so.
How long is a star a supergiant?
The supergiants are the most massive stars out there, ranging between 10 to 70 solar masses, and can range in brightness from 30,000 to hundreds of thousands of times the output of the Sun. They have very short lifespans, living from 30 million down to just a few hundred thousand years.
How big are giants and supergiants?
Masses of giants and supergiants may be 10 to 30 times that of the Sun, but their volumes are often 1,000,000 to 10,000,000 times greater. Thus, they are low-density “diffuse” stars.
Is a supergiant bigger than a red giant?
Supergiant are exponential bigger than a red giant with largest one we know 1700 times the size of our Sun. When our Sun becomes red giant it's theorised to bloat up to around 256 times its initial diameter meaning most supergiants will be 3 – 8 times bigger than a star roughly 1 solar masses like our Sun.
Is a supergiant bigger than a galaxy?
Supergiant stars are stars that may have the mass of 10 to 70 stars, any more than that and it is rather unstable and often explodes into a supernova. In terms of mass, a galaxy, no matter how small would be more massive than a supergiant star. In terms of size a galaxy would still be larger than a supergiant star.
What makes a star a supergiant?
Supergiants develop when massive main-sequence stars run out of hydrogen in their cores, at which point they start to expand, just like lower-mass stars. Unlike lower-mass stars, however, they begin to fuse helium in the core smoothly and not long after exhausting their hydrogen.

Which is the biggest star in the world?
UY ScutiThe 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.
Will our Sun become a red giant?
In a few billion years, the sun will become a red giant so large that it will engulf our planet. But the Earth will become uninhabitable much sooner than that. After about a billion years the sun will become hot enough to boil our oceans. The sun is currently classified as a “main sequence” star.
Is the Sun a supergiant?
The Sun will never become a supergiant. It will become a red giant, which is much different. Additionally, the mass of the Sun will not increase.
What's bigger than the universe?
No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.
Which is the biggest thing in universe?
the Hercules-Corona Borealis Great WallThe 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's bigger than the red giant?
Blue supergiant stars are in between the size of red giants and blue hypergiants. They are very luminous and very hot. They become blue supers through radiation pressure, convection and the large burning of hydrogen. These will eventually become red supergiants over time.
What is the difference between supergiants and giants?
Because supergiants are so massive, the core temperature gets much hotter than in giants, so supergiants can fuse elements heavier than hydrogen and helium. But to support their tremendous mass, supergiants burn up their fuel much more quickly.
How big are supergiants compared to our Sun?
The largest supergiant stars can be more than 1500 times larger than our Sun. This makes them over 2,000 million km across. However, supergiants actually don't contain thousands times more mass than the Sun.
What are the characteristics of giants and supergiant?
Large Surface Areas That is why they are called giants and supergiants: they are much larger stars than the corresponding main sequence stars. For example, a giant star like Arcturus is almost twenty times larger than the Sun, and the supergiant star Antares is more than 300 times larger than the Sun.
What is the difference between supergiant and supergiant?
Going by the picture at the bottom, giant stars are say 10x bigger than our own sun such as Pollux, supergiant stars are 100x bigger than ours and hypergiants are 1000x and above.
What is a supergiant star?
Supergiant star, any star of very great intrinsic luminosity and relatively enormous size, typically several magnitudes brighter than a giant star and several times greater in diameter. The distinctions between giants (see also giant star), supergiants, and other classes are made in practice by. Supergiant star, any star ...
What are the different types of stars?
Overview of several types of stars, notably the red dwarf, red giant, supergiant, white dwarf, and brown dwarf.
What is the largest supergiant?
Among the largest supergiants ever discovered are VV Cephei, V354 Cephei, KW Sagitarii, KY Cygni, and the Garnet Star. Supergiant stars come in two flavors, red and blue. Blue supergiants are usually the hottest stars in the universe.
How many solar radii are there in a supergiant?
In regards to their radius, supergiants vary greatly, from 30 to 500, or even exceeding 1,000 solar radii.
How do supergiant stars form?
Supergiant stars form out of massive main-sequence stars that have run out of hydrogen in their cores. This causes them to expand greatly, similarly to low-mass stars, however, they begin to fuse helium in their core not long after exhausting their hydrogen supplies.
What is the spectral type of a red supergiant?
Blue supergiants are also rare, their spectral type is usually OB, B. Some examples of red supergiants are Antares, Betelgeuse, and Mu Cephei.
Why do supergiant stars have higher nitrogen levels?
Post-red supergiant stars have a higher level of nitrogen relative to carbon due to convection of CNO-processed material to the surface and the complete loss of the outer layers.
What temperature do supergiant stars have?
The temperature range of supergiant stars spans from around 3,450 K to 20,000 K.
Why do supergiant stars have a short lifespan?
Supergiant stars burn very quickly through their hydrogen supplies, thus the reason why they have short lifespans.
What Does It Take to Be a Supergiant?
A red supergiant is an aging giant star that has consumed its core's supply of hydrogen fuel. Helium has accumulated in the core, and hydrogen is now undergoing nuclear fusion in the outer shells. These shells then expand, and the now cooler star takes on a red color. They are the largest known stars.
Which supergiant has the largest radius?
The largest hypergiant is VY Canis Majoris, which is the largest of all supergiants and has a radius 1,800 times larger than our sun's. While many average-sized stars (like our sun) will live for billions of years, red supergiants only last for hundreds of thousands of years. Key Definitions.
What happens to the helium in the core of a red supergiant star?
Apart from increasing in size and changing color, red supergiant stars kick off the fusion in their cores again. The helium that accumulated during their main sequence phase begins to fuse into carbon.
What happens when a supergiant crashes into the core?
As they crash into the core, it leads to a wild supernova explosion. The remnants of the once great red supergiant will then form either a neutron star or a black hole. Red supergiants are aging giant stars that have consumed their core's supply of hydrogen fuel.
What happens when the pressure of a supergiant is high enough?
When the pressure gets high enough, the carbon will fuse into oxygen, and these changes will continue as heavier and heavier elements are fused. As the different types of fusion occur, the red supergiant will swell and contract, thus making it variable in size.
What happens at the beginning of the end of a star?
The beginning of the end is an accumulation of iron in the core. Iron fusion cannot proceed without outside energy, and when iron accumulates, the core's energy source has expended. Without the forces pushing outwards, the star's outer layers come crashing inwards.
What constellation is Betelgeuse in?

Overview
Evolution
O type main-sequence stars and the most massive of the B type blue-white stars become supergiants. Due to their extreme masses, they have short lifespans, between 30 million years and a few hundred thousand years. They are mainly observed in young galactic structures such as open clusters, the arms of spiral galaxies, and in irregular galaxies. They are less abundant in spiral galaxy bulges and are rarely observed in elliptical galaxies, or globular clusters, which are c…
Definition
The title supergiant, as applied to a star, does not have a single concrete definition. The term giant star was first coined by Hertzsprung when it became apparent that the majority of stars fell into two distinct regions of the Hertzsprung–Russell diagram. One region contained larger and more luminous stars of spectral types A to M and received the name giant. Subsequently, as t…
Properties
Supergiants have masses from 8 to 12 times the Sun (M☉) upwards, and luminosities from about 1,000 to over a million times the Sun (L☉). They vary greatly in radius, usually from 30 to 500, or even in excess of 1,000 solar radii (R☉). They are massive enough to begin helium-core burning gently before the core becomes degenerate, without a flash and without the strong dredge-ups t…
Supernova progenitors
Most type II supernova progenitors are thought to be red supergiants, while the less common type Ib/c supernovae are produced by hotter Wolf–Rayet stars that have completely lost more of their hydrogen atmosphere. Almost by definition, supergiants are destined to end their lives violently. Stars large enough to start fusing elements heavier than helium do not seem to have any way to lose enough mass to avoid catastrophic core collapse, although some may collapse, almost wit…
Well known examples
Supergiants are rare and short-lived stars, but their high luminosity means that there are many naked-eye examples, including some of the brightest stars in the sky. Rigel, the brightest star in the constellation Orion is a typical blue-white supergiant; Deneb is the brightest star in Cygnus, a white supergiant; Delta Cephei is the famous prototype Cepheid variable, a yellow supergiant; and Betelgeuse, Antares and UY Scuti are red supergiants. μ Cephei is one of the reddest stars visible t…
