What is the surface temperature of a red giant?
The surface temperature of a red giant is, at most, 5000 Kelvin.
Which types of star has low temperature and high luminosity?
A red giant star.
What is the average temperature of the red giant star?
Red giants have temperatures between about 5,000 and 6,700 degrees Fahrenheit.
Why is a red giant called a red giant?
A red giant is called so because it appears red in color due to its lower surface temperature compared to a younger star. As it expands and cools during its later stages of evolution, it becomes larger and brighter, hence the name "red giant."
How can a red giant become brighter if it now has a lower surface temperature?
A red giant can become brighter if its core temperature increases due to increased fusion reactions. Even though the surface temperature decreases, the overall luminosity of the star can increase if the core fusion rate intensifies, producing more energy.

How hot is the great red sun?
According to Wikipedia, a red giant has a surface temperature of 5000 K or less.
What type of star is ras algethi?

Is a red super-giant hot?
The colour of a star is a good measure of the surface temperature.
How can a red giant become brighter if it now has a lower surface temperature?
A red giant can become brighter if its core temperature increases due to increased fusion reactions. Even though the surface temperature decreases, the overall luminosity of the star can increase if the core fusion rate intensifies, producing more energy.
How cold is a red giant?
The surface temperature of a red giant star can range from about 2,600 to 3,700 degrees Celsius. This is relatively cooler compared to younger main sequence stars like the sun, which has a surface temperature of about 5,500 degrees Celsius.
