Is there a term (compound word or phrase would be acceptable) one could use to refer to either the Moon or the Sun depending on the time of day? Other than the big shiny thing in the sky.
I'd use it in a sentence like: "The Sun/Moon is green because..."
The Sun is a star and the Moon Earth's satellite so I can't say planet or star. They both emit strong light toward the Earth so maybe there's something about that.
