Hypergiants are stars with a tremendous mass and luminosity, showing signs of a very high rate of mass loss. Hypergiants are very luminous stars, up to millions of solar luminosities, and have temperatures varying widely between 3,500 Kelvin and 35,000 Kelvin.
Because of their high masses, the lifetime of a hypergiant is very short, only a few million years compared to around 10 billion years for stars like the Sun.
See link for a pictorial representation of our Sun compared to the largest known hypergiant.
What else can I help you with?
What class of stars are the largest?
The largest class of stars are known as hypergiants. These massive stars have very high luminosities and can be hundreds of times bigger than the Sun. Examples include stars like UY Scuti and Betelgeuse.
Which stars have the shortest lives?
Massive stars, such as blue supergiants and Wolf-Rayet stars, have the shortest lives because they burn through their fuel much faster due to their intense nuclear reactions. These stars can live for only a few million years before ending in a dramatic supernova explosion.
Do blue stars and red giant stars have similar brightness values?
Blue stars are generally much brighter than red giant stars. Blue stars are very hot and luminous, emitting a larger amount of energy compared to red giants, which are cooler and typically less bright.
True or false Red stars are hotter than whittish- blue stars?
False. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
What is the weight of star?
Stars do not have weight they have mass. Our Sun is said to be one solar mass or 1.98892×1030 kg. There are stars smaller than our Sun (read dwarfs) which can be down to 0.075 solar masses and stars much much bigger than the Sun (Hypergiants) which can reach 80-150 solar masses.
How many Hypergiants are in the Milky Way?
Hypergiants are very rare and they have a ver short lifespan, and thus they are difficult to observe.
What are the biggest stars in the universe?
Red hypergiants.
Why doesn't hypergiants have planets?
We don't actually know that they don't; however, as hypergiants are quite massive, it's hard to detect the slight perturbation a planet would have on one.
What is bigger blue hypergiants or red hypergiants?
Depends on how you want to classify bigger. Mass or diameter. VY Canis Majoris is a red hypergiant and has the largest diameter of any known star. See related questions for both answers
How many hyper giant stars exist in the universe?
Hypergiants are relatively rare. Only a few stars become hypergiants, and they don't last very long (only a few million years). Probably a few in every major galaxy.
What is the Coolest largest and brightest than most main sequence stars?
Red giants, red supergiants and red hypergiants.
Do black holes destroy hypergiants?
Black Holes can destroy anything in their path. Only when the 'Hypergiant' is within range of the Black Hole.
What is the name of a very large star?
The largest known stars are the red supergiants or hypergiants. One example, the largest known star, is VY Canis Majoris.
What is the hottest star in your universe?
it's the blue hypergiants, like Eta Carinae and R136a1, which are probably the hottest stars in the Universe. These are estimated to be around 40,000 degrees Kelvin.
Which of the stars are considered a dwarf star?
Basically, all stars that aren't "giants", "supergiants", or "hypergiants" are considered dwarf stars. This means that all stars on the main sequence are dwarfs.
Example of a medium size star?
Mira, thuban or Arcturus are some examples. Giants are around 10 to 100 times larger than our own sun (by diameter). Supergiants and hypergiants are bigger still.
Are the largest stars known red super giants?
No, the largest star known is a Red Hypergiant (vy canis majoris) which are much larger than supergiants. Most of the largest stars are red hypergiants followed by red supergiants.
