Is the 'Sun' specifically the name of the Solar System's star..?

Question

or can the Sun refer to any star that man/machine happen to be observing or in close proximity too.

Is the word 'Sun' a noun?

Answer 1

the suns real name is sol

Answer 2

Our sun is actually named "Sol" and "Sun". There are two astronomical definitions for "Sun".

1. "Sun" (with a capital "S") is the the Earth's local star, and the star it orbits in our solar system.

2. "sun" can be used as a noun. It is basically a sort of a slang term for a local star.

A "local star" is the main star of any solar system. So lets pretend there is this planet... Bob... that orbits this star... Phil.

To Bob, Phil is its local star because Bob orbits Phil. So to Bob, Phil is its "local star" and is also its "sun" though his name is really "Phil". To Earth, Phil is not its local star, and therefor Phil isn't his sun becuase he does not orbit it. To Earth, he is just "Phil". Make sense?

Answer 3

Our Sun is technically named "Sol", and the planets and other things around it compose the "Solar" system.

Answer 4

Our sun is called "The Sun" all other suns are just suns.

Answer 5

In modern times our star is the Sun. With a capital letter. Sol is a name used in very early astronomy and astrology. We live in the Milky Way Galaxy. Other galaxies are small letters our Galaxy is a capital letter like our Sun.

Answer 6

Yes, our solar system, because there are many others out there!

Answer 7

I never got that either.  What makes a star a 'sun'?  Why call ours "The Sun"?  But apparently it's actual name is Sol.  But why not call, for instance, "Sirius", "The Sun"?  LOL:)

Answer 8

yes, sun is a noun and u can use it for every star that is center of a solar system. sol is just the Latin word for sun.

btw there are binary star systems not exactly sure whether those are considered suns then. I guess you could, too because you talk about moons and not natural salites either.

But since you live on earth, it would make sense to talk about stars when you mean other suns in different solar systems. You might just confuse people otherwise.
