It emphasizes the immense scale of the universe, focusing on the largest known star, stephenson 2 18, which is a red hypergiant with a size of 2150 solar radii and a luminosity nearly half a million times that of the sun.
A comparison of star sizes. this illustration compares the different masses of stars. the lightest weight stars are red dwarfs. they can be as small as one twelfth the mass of our sun. the heaviest weight stars are blue white super giants. they may get as large as 150 solar masses. our sun is between the lightweight and heavyweight stars. The terms giant and dwarf were coined for stars of quite different luminosity despite similar temperature or spectral type (namely k and m) by ejnar hertzsprung in 1905 [3] or 1906. [ 4 ] giant stars have radii up to a few hundred times the sun and luminosities between 10 and a few thousand times that of the sun . Unveiling uy scuti: the biggest star. uy scuti holds the prestigious title of the largest known star, a red supergiant star that dwarfs even the most luminous stars in our night sky. as a hypergiant star, uy scuti's immense size is almost incomprehensible, with a radius about 1,700 times larger than that of our sun. Size comparison of a hypothetical quasi star black hole star (diameter of ~10 billion kilometres or ~7,187 solar diameters, mass of 1000 solar masses) and several known giant stars: stephenson 2 18 (~2150 solar diameters), vy canis majoris (~1420 solar diameters, ~17 solar masses), betelgeuse (~887 solar diameters, ~11.6 solar masses), the pistol star (~306 solar diameters, ~27.5 solar masses.

The biggest stars are blue stars, and they are particularly hot and bright. in the middle are yellow stars, which includes our sun. somewhat smaller are orange stars, and the smallest, coolest. They may contain the mass of one or two suns but are often just 20 to 40 km in diameter. white dwarf stars are a bit bigger often similar in size to our planet earth . the largest supergiant stars can be more than 1500 times larger than our sun. this makes them over 2,000 million km across. however, supergiants actually don't contain.
