The sun is not an illuminated object. It is a luminous object, meaning it produces its own light.

Here's why:

* Nuclear Fusion: The sun generates light and heat through nuclear fusion, a process where hydrogen atoms combine to form helium, releasing enormous amounts of energy.

* Energy Emission: This energy is emitted as electromagnetic radiation, including visible light.

Therefore, the sun is the source of light, not something that reflects light from another source.
