• Question: Why does the sun appear a yellow/orange colour? Is it something to do with the reflection and white light?

      The sun is really almost white. It appears yellow for the same reason that sky appears blue: Blue light scatters more off particles in the atmosphere, and the remaining light that travels straight to us is therefore yellow.
