      I think that it is orange – but appears more yellow here on Earth

      Hiya Lucyja 🙂

      The sun is spinning swirling mass of fire. It’s sort of orangey yellow red and the surface is 5500 degrees Celsius 🙂

      It’s a pinkish-yellow – the sun actually emits light of quite a broad set of wavelengths but there is a simple law – Wien’s law that relates temperature to colour

      The sun emits white light, but it looks yellow to us when we see it high in the sky because the blue light is scattered by the atmosphere (which is why the sky looks blue).

      When the sun is low in the sky, it looks red. This is because the light from the sun has had to travel through more atmosphere to get to us, so more of the blue light has been scattered, leaving the sun looking red.

      Cool eh!
