Supergiants can contain 8 - 200 times the mass of the Sun! They also shine brightly. One supergiant can be as bright as a million Suns. The colour of supergiants can be red or blue. Red supergiants have low surface temperatures, below 4,100 K.

WebFusion creates extra radiation pressure and this will cause the Sun to expand. The outer layers of hydrogen will decrease in temperature, which will make them redder, and the Sun will then be a red giant. All main sequence stars that are about 1/5 to 10 times the mass of the Sun will become red giants. [1] Figure 12.1 Image credit

WebPlanetary nebulae seem to mark the transition of a medium mass star from red giant to white dwarf. Stars that are comparable in mass to our Sun will become white dwarfs within 75,000 years of blowing off their envelopes.
