Do our sun and moon have names?
We seem to have named every moon orbiting other planets. Why haven't we named our own moon? And for that matter, why doesn't our sun have a name since we name or number stars?
I get the confusion for the moon, as there are many celestial objects which are called moons, so "The Moon" may not seem like a name. But there is only one Sun - it's a completely unique identifier for our star. What would suggest that this commonly used, unique identifier is *not* a name?
What is "Earth's star" supposed to mean? That title edit didn't made the question far more confusing. The grammatically correct version by Glorfinel was clearer. I'm rolling back
@JamesK It's not "ours" but okay. It's not possible that a cogent person would not know what “Do Earth's star and moon have names?” means, though I still struggle to know if it should be “Does”. Planets are generally understood to have stars around which they orbit. It is suspected that there are some exceptions, but those are exceptions (see what I did there?)
This question is prima facie evidence that the ordering of answers needs to be changed. The accepted answer is wrong.
I'll note that the sun and moon have at least a dozen different names in different human languages, many of them linked with gods.
Most people around the world call their tribe or people "People" in their language... a surprising number of mountains have the name "White Mountain" in the respective language, and significant rivers are often called "Big River". Even in the U.S. there's more than one "Big River".
"The Sun" is fine as long as you're not leaving our solar system; less so "the Moon" when there are hundreds of planetary satellites in this system alone.
In science fiction as varied as Isaac Asimov and ''Star Trek'', the names are Sol and Luna.
EDIT: My point is that sci-fi authors are writing from the point of view of societies with many "suns" and "moons", and those societies have adopted the classical terms as the "current" official names.
The latter sentence is a bit weird. Sol is the norse word for Sun (found e.g. in "solar"). https://en.wikipedia.org/wiki/S%C3%B3l_(sun). Luna is the latin word for the moon (as witnessed by "lunar"). (Both being the names of their respective gods who were responsible for those phenomena, but that's beside the point.) Has nothing to do with SciFi or those authors...
"The Moon" is also fine if you don't leave Earth, which is a valid assumption for the vast majority of people using the term.
Strictly speaking, "sól" is the Old Norse word, and "sol" is the Latin word. The two are cognates, both coming from the same Indo-European root that *also* means "sun".
@DavidHammen It's a little strange, isn't it, since older answers seem to cover it pretty well...
@DavidHammen it's a fine answer because of the edit: *sci-fi authors are writing from the point of view of societies with many "suns" and "moons", and those societies have adopted the classical terms as the "current" official names.* The other answers are also right: the names **are** The Sun and The Moon.
