type of star with a radius 10-100 times, and luminosity 10-1000x that of the Sun
A giant star is a massive star with a radius and brightness much larger than our Sun—typically 10 to 100 times wider and 10 to 1,000 times brighter. Giant stars matter because they represent a crucial stage in stellar evolution and help astronomers understand how stars age and eventually die.
