A star's radius is the distance from it centre to its visible surface. The bigger the star, the larger the radius.
The radius is not the best means of comparing stars, it is perhaps better to compare stars by their mass.
A process called gravitational collapse is used by solar radii to describe the sizes of stars including the subgroups of white dwarfs giants and super giants.Solar radii be used to describe the sizes of stars including the subgroups of white dwarfs giants and super giants through a process called gravitational collapse.
Supergiants have been observed for centuries by astronomers, but their classification and understanding were refined over time. The term "supergiant" was first used by astronomer Gerard Kuiper in the 1930s to describe stars much larger and brighter than giants. Subsequent studies by astronomers such as Cecilia Payne-Gaposchkin and Ejnar Hertzsprung contributed to our understanding of these massive stars.
No. Only massive stars can become supergiants.
The biggest and brightest stars are called supergiants. These stars are much larger, hotter, and more luminous than our Sun. Examples of supergiants include Betelgeuse and Rigel in the constellation Orion.
No, the sun is a relatively average-sized star known as a "yellow dwarf." There are many much larger stars in the universe, including red giants and supergiants.

Giants and super giants are considered stages in the life cycle of a star.
Giants or supergiants
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.
The stars that are like supergiants are called "red giants" or "red supergiants".
Red giants, red supergiants.
White Dwarfs, Supergiants, and Red Giants are stars that are found in the sky.
They could be Blue Giants, or Red Giants, or Red Supergiants.
Yes, there are. The classic red giants that come from sun- like stars, and red supergiants come from blue giants.
According to Wikipedia giants have absolute magnitudes around 0 to -1 while supergiants have absolute magnitudes around -5 so they are 50-100 times brighter (5 magnitudes difference equals 100 times brighter).
The three extra groups on the H-R diagram are white dwarfs, red giants, and supergiants. These groups represent stars in different stages of their evolution based on their luminosity and temperature. White dwarfs are small, hot stars near the end of their life cycle, red giants are large, cool stars in the later stages of their life cycle, and supergiants are massive, luminous stars.
