Only a very small fraction of stars are red giants at any given moment. But they do stand out, because they are extremely bright.

The theoretical maximum mass that a star can have is about 150 times the mass of our Sun. Anything larger, and the fierceness of the solar radiation would push the excess mass away.
A star that's 150 times the mass of our Sun will be about a thousand times larger in diameter. If such as star were placed in the center of our solar system, it would swallow up Mercury, Venus, the Earth, Mars and the asteroid belt.
Very massive stars burn hotter and brighter, are much larger and consume their hydrogen fuel far more quickly that the Sun does. Our Sun is about 4.5 billion years old, and we expect it to continue to shine much as it does now for another 4 billion years or so. A super-massive star will form, shine very brightly for a few million years or less, and die spectacularly in a supernova explosion that will leave behind a "black hole in space", a place where gravity is so strong that not even light can escape from it.
Betelgeuse is a very massive supergiant star, about 10 million years old. It is already approaching the end of its life, and will probably go supernova within the span of humanity.
Red giants. By the way, what if it was a white star.
Blue giants and red dwarfs are both types of stars, but they are quite different. Blue giants are massive and hot stars that shine brightly, while red dwarfs are smaller, cooler stars that emit a fainter light. Blue giants are more short-lived and evolve faster compared to red dwarfs, which have much longer lifespans.
A star might begin to die after its main sequence. It'll balloon to a very big size. They're called red giants because the star is big and red. A red giant can die, though. Red giants die when their surface sheds into a cloud called a planetary nebula. Its core becomes a white dwarf. Our sun will go through this path.
Red Giants:)
They are red giants.
red giants
Yes, there are. The classic red giants that come from sun- like stars, and red supergiants come from blue giants.
Generally red giants are bigger, but really it has more to do with how hot they burn. Blue giants burn hotter and have more mass.
Red Giants are 20 to 100 times bigger than the Sun.
Yes. The lowest mass stars are red dwarfs while many older stars turn into red giants and red supergiants.
Well light wise the highest category would be blue giants, red giants, and super red giants.
Red giants. By the way, what if it was a white star.
No, red giant stars are not the largest stars in the universe. There are stars known as supergiant and hypergiant stars that are even larger than red giants. These stars can be hundreds to thousands of times larger than our Sun.
White Dwarfs, Supergiants, and Red Giants are stars that are found in the sky.
Yes, Giants alternate jerseys or pracitce QB jerseys are red.
They could be Blue Giants, or Red Giants, or Red Supergiants.
The New York Giants Alternate Red jersey has been worn 3 times by the Giants and has been retired as of 2009.
