Red super giants are the largest stars in the universe in terms of volume, although they are not the most massive. Red supergiant stars are what become of large stars (stars that are 10 or more times massive than our own) towards the end of their life, once the hydrogen fuel has mostly been exhausted, and the helium burning stage is in effect. These stars are relatively cool, with surface temperatures around 3500-4500 degrees Kelvin, but have huge sizes. The largest known red super giant in the Galaxy is a hyper giant called VY Canis Majoris, which radius is around 1500-2000 times that of our sun. The radius of most red giants is between 200 and 800 times that of the sun. If this largest known star were in our solar system, then its surface would extend out further than Jupiter's orbit, maybe even approaching Saturn's orbit.

above the main-sequence stars
What do we call a large family of millions of stars?
Red giants. By the way, what if it was a white star.
What forms when helium nuclei combine?
If the central temperature of a star exceeds 100 million Kelvins, as may happen in the later phase of red giants (stars) and red supergiants, then helium can fuse to form beryllium and then carbon.
What cool and bright stars are located in the upper right of the H-R diagram?
In the usual position of the axes, the upper-right is populated by giants and supergiants.
Cooler larger and brighter than most main sequence stars?
Large stars - such as red giants, or supergiants - usually have a relatively low surface temperature.
How long do red supergiants live?
Red Supergiants tend to live about half a million years.(:
Why does fusion continue in red supergiants?
fusion continues in red supergiants because they are bigger than red giants so they would have more molecules. ~.~
What are the universe's biggest stars?
Red supergiants
What stars are extremely luminous but not hot?
Red giants, red supergiants.
Which star is likey a super giant?
The stars that are like supergiants are called "red giants" or "red supergiants".
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.
What type of stars are Betelgeuese and Antares?
Both are red supergiants.
What are larger and more luminous than red giants?
Supergiants are bigger and more luminous than the red giants. Supergiants are stars that have a mass that is eight times more than the sun.
