      The sun is a very average star and its about 6000 degrees. The colour of a star tells you how hot it is. The hottest stars are blue and can be as hot as 30,000 degrees. Red stars are the coldest but could still be as hot as 3000 degrees

      The sun is a very standard star with a surface temp of about 4000-6000 degrees. The temperature in the core gets to about 25 million degrees! There’s a really weird effect in the corona (a sphere on the outer edge of the sun) where the temperature suddenly jumps to about 2 million degrees, we don’t know why! It’s called the coronal heating problem.
      The inside of some stars can get up to 200 Million degrees! We use a special technique called asteroseismology to see inside of stars far away!

      Great Question,

      Ryan
