It's possible you meant one of the following:
* Natural satellite: This refers to a celestial body that orbits a planet or other larger object. The most common example is our moon, which is a natural satellite of Earth.
* Satellite: This term broadly refers to any object that orbits another object in space. It can be natural (like the moon) or artificial (like the International Space Station).
* Satilite: This is likely a misspelling of "satellite".
If you can provide more context about where you encountered the term "natural satilight," I might be able to give you a more specific answer.
