The size of red giants can be estimated by comparing them with stars of known size and that have the same:
Earth
dimmest
absolute magnitude and temperature
50
surface temperature
sizes
brightest
main-sequence stars
How much more massive are the hottest blue stars when compared to our Sun?
Earth
dimmest
absolute magnitude and temperature
50
surface temperature
sizes
brightest
main-sequence stars
Any difference in the brightness of two stars having the same surface temperature is due to their relative:
Earth
dimmest
absolute magnitude and temperature
50
surface temperature
sizes
brightest
main-sequence stars
Main-sequence stars that have the highest temperatures are the:
Earth
dimmest
absolute magnitude and temperature
50
surface temperature
sizes
brightest
main-sequence stars
The Hertzsprung-Russell diagram shows the relationship between a stars:
