Largest Known Stars in Our Universe
Transcript of Largest Known Stars in Our Universe
The Death Of Canis Majoris
The star is fairly "old," and has almost outlived its lifespan of about 4-5 million years. Once it dies, it will explode into what is called a supernova, and creates millions of new atoms in our universe.
The star VV Cephei is about 5000 light years away from Earth and has a solar radius between 1050-1900.
Although it is one of the largest star in the universe, it is not big enough to qualify as a hyper-giant. It is only large enough to be considered a red super-giant.
V838 Monocerotis is the first L-type super-giant know to man. It is about 20,000 light years from the sun, and has a solar radius of 380 squared.
The largest known star in our universe is Canis Majoris, and is part of the constellation, Canis Major. It is roughly 97,600,000 kilometers in diameter, and 4,892 light years away from earth.
Top 5 Largest Stars
Types of Stars
The different types of stars recorded in our galaxy are usually ranged by size and color. The largest stars are "hyper-giants, and are usually red in color. The smaller and more common type of star is the red dwarf star. Our sun is a red dwarf star, and although it seems pretty big, it is smaller than a snowflake compared to some of the larger stars in the universe. Some other types of tars are red giants, super-giants,neutrons, and white dwarfs.
Canis Majoris is about 30-40 million times bigger than our sun

End Of V838 Monocerotis' Lifespan
This super-giant is on the near verge of it's death, which will most likely end in a helium flash.
What Is a Helium Flash?
A helium flash is when the core of a dying star ignites helium fusion, which disrupts the star, but doesn't destroy it.
V838 Monocerotis and its light echos
The star WOHG64 had a solar radius of about 1,540-1,730, 1540 times bigger than the sun. Its distance from the earth is about 163000 light-years.
Although these stars are numbered from 1-5, the stars listed are not in order from largest distance compared to the other listed 5 stars. They are the largest in the universe, but i found varying research about the order of these stars from largest to smallest.
WOHG64's Mass Loss
This massive star is slowly deteriorating and losing lots of its total mass. It is surrounded by a huge torus of gas and dust, and, according to research, is most likely experiencing unstable, violent mas loss
V354 Cephei has a radius of 690-1,520 and is 9000 light-years away from the sun.
Description of V354 Cephei
This red super-giant star is 690-1520 times bigger than the sun. It is located in the Milky Way and is a part of the constellation Cepheus.
Star V354 Cephei
In conclusion, the stars Canis Majoris,VVCephei,V838- Monocerotis,WOH G64,and V354 Cephei are the 5 largest stars in the universe know to man so far. These stars could always be subtracted from the list by the discovery of a new star, or the death of one of these stars.
