How hot are stars?

In: Planetary Science, Stars [Edit categories]

Answer:

All stars have different temperatures, depending on their mass and period in their life cycle. The hotter a star is, the brighter it will appear.

The stellar classification [See link] in order of temperature. Our Sun is classed as yellow.

Blue > 30,000 Kelvin
Blue to blue white 10,000 - 30,000 Kelvin
White 7,500 - 10,000 Kelvin
Yellowish White 6,000 - 7,500 Kelvin
Yellow 5,200 - 6,000 Kelvin
Orange 3,700 - 5,200 Kelvin
Red 1,000 - 3,700 Kelvin
Brown < 1,000 Kelvin
Black 0 Kelvin

See link [Kelvin] for conversion ratios.

These temperatures are the surface of the stars. The cores of the stars are much hotter, around 15 million degrees for our sun.
