If other planets moon has a name why not our moon?

The "Moon" is the name of Earth's natural satellite.

The English use of the word “Moon” was derived from moone around 1380. It developed from mone (1135), which derives from Old English mōna (dating from before 725), which ultimately stems from Proto-Germanic mǣnōn.

For most of history, our Moon was the only one of its kind known to man. Like the Sun, it was considered to be unique.

After the telescope was invented, it was found that other planets also had bodies in the same type of configuration – in orbit around the planet. For lack of a better name, these bodies were also called moons, but as a description.

In the English language, “Moon” is capitalized when used as its name. When used as a description it is not capitalized. Notice that in the sources below.

Technically our moon has no official name but it has many unofficial names. Luna for example is not an official name for our Moon it's just the Latin word for moon. Selene is another name you could use for our Moon but again that's just the Greek for Moon.

Our moon does have an English name, it's called "The Moon". The M in moon is capitalized when used as our moon's proper name but small when referring in general to any natural satellite.

The Moon therefore has many names in every language. The International Astronomical Union whose job it is to give official names have declined to give the Moon an official name but have recommended the capitalization convention that I outlined but won't impose a convention for every language.

We do have a name for it, it is called the "Moon". It was the only "Moon" we ever knew so we have always called it that, when scientists discovered objects orbiting other bodies they were classified as Moons but to avoid confusion in usage any moon orbiting another planet is called by a different name.

Moon (with a capital M) is the official name of our natural satellite.

The use of the word "moon" (with a small m) as a simile is acceptable in literature and in general writing, but is not an official appellation in astronomy.

Sure, if we say the "moons of Jupiter", most everyone understands... or do they? (when Galileo discovered the first four, he officially called them "planets").

The official general term is "satellite", and our Moon is the natural satellite of Earth.

Sun (capital S) is the official name of our star. The Latin name was Sol, therefore the Solar system is OUR system of planets. Other systems of planets are NOT "solar systems". It is acceptable in general writing to use the simile "sun" (small s) when talking about stars, especially if they have planets around them -- but that is not an official astronomy appellation.

Earth's moon is so iconic and has been known about for so long that it gets the title of The Moon. It was the first moon we knew about.

It's called Luna

Luna is what our moon is called. It had a different name long ago when it was first colonized.

If "Moon" isn't good enough for you, then how about Selene (it's Greek name) or Luna (Roman name)?

I quite like the name Luna.

The name of OUR moon is LUNA

Other planets have natural satellites, too, but only ours is "The Moon."
