How hot do red giants get? How does this compare to our sun?

Answer 1

Red giant stars have a surface temperature between 3,000 and 5,000K.

The colour of a star depends on its surface temperature. Red giant stars are so massive that their surface temperature is relatively low. Typically red giant stars have surface temperatures of 3,000K - 5,000K.

In contrast the surface temperature of the Sun is almost 6,000K.

The cores of stars are much hotter. The Sun's core is about 14,000,000K.

The surface temperature of red giants is typically between 5,000 and 6,000 Kelvin, which is colder than the surface temperature of our Sun, which is approximately 5,500 degrees Celsius.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
