Stars can be organized by size and temperature into four groups: dwarf stars, main sequence stars, giant stars, and supergiant stars. Into which group does the Sun most likely fall?
dwarf stars, because the Sun is much smaller than most other stars
giant stars, because the Sun is much larger than most other stars
supergiant stars, because the Sun is one of the largest stars
main sequence stars, because the Sun is of average size

Main sequence stars appear as a band on Hertzsprung-Russell (HR) diagrams. The HR diagram below shows the relationship between absolute brightness and temperature. Absolute brightness is measured here using a brightness scale, called absolute magnitude.
In a main sequence star, what is the relationship between a star’s absolute brightness (measured as absolute magnitude) and its temperature?
The lower the temperature, the brighter the star
The higher the temperature, the brighter the star.
Most stars have the same temperature, but differ in absolute brightness
Most stars have the same absolute brightness, but differ in temperature
