Betelgeuse, a red giant, is about 700 times bigger than the sun and about 14,000 times brighter. “We have found stars that are 100 times bigger in diameter than our sun. Truly those stars are enormous,” NASA says on its SpacePlace website. “We have also seen stars that are just a tenth the size of our sun.”

What is the smallest thing in the universe?
Quarks are among the smallest particles in the universe, and they carry only fractional electric charges. Scientists have a good idea of how quarks make up hadrons, but the properties of individual quarks have been difficult to tease out because they can’t be observed outside of their respective hadrons.
Who is bigger sun or star?
