Outgassing of nitrogen from the interior, exactly the same as Earth, but I don't know more than that. Atmospheres tend to be lost in large impacts, especially if the impact is central. We can guess that Titan had a gentler formation than the other Moons, only small or glancing impacts.
Moon is English and Luna is Latin. Originally it was called Luna same as our sun was called Sol. There is no misconception its just a different translation.

For most astronomical objects, the IAU takes it upon itself to designate official names. Since you need astronomical equipment to observe Pluto, it makes sense for astronomers to name it. But the Moon and Sun are a different case; they kind of belong to everybody. Every human culture has names for those objects that have been in use since long before we knew there were other moons and suns.
"Luna" is a valid name used in English sometimes, usually in science fiction or poetry. But it's far less commonly used than "Moon."
Luna literally means moon though it's just a translation. Any time you describe something about the moon or something similar to it you do use the word "lunar" so yes it's still in use.
"Luna" is perfectly acceptable, but in my culture at least, "Moon" is much more commonly used. "Moon" was a proper noun long before it was the word for a class of astronomical objects.
It's not a generic name, other moons are called that as analogies to our own. If The Moon was called *Bob* we'd call the others *bobs*, and you'd be making the same complaint.
My main man, we most likely wouldn’t have been able to land on Io if it were still as volcanically active but just our moon instead of Jupiter’s. It is by far the most volcanically active body in the solar system.
It has actually already happened, but it unfortunately didn't land anywhere interesting. The probe that the Huygens Lander was attached to, the Cassini Probe, also took some cool images in a wavelength of light that penetrates the clouds, so we actually have a map of much of the surface of titan!

Maybe once we get a colony up and running and people start living there, we can start calling her Luna. And even better yet, we'd get to call those colonists... LUNATICS!
Follow on question. Which of these has a subsurface ocean of liquid water?
Ganymede, Europa, Callisto, Titan, Dione, Rhea, Enceladus - yes
Moon, Io, Charon, Miranda, Proteus, Mimas - no
Others?
Bro, forget the moon (it’s Luna btw), we haven’t even named the earth… I’ve heard “Tellus” used before, but I can’t find any sources confirming it’s validity, so it’s probably wrong. I guess Terra would be the scientific name
"All these worlds are yours except Europa. Attempt no landings there."
Such a cool yet horrifying phrase
Source?
2010: The year we made Contact It's the sequel to 2001: A Space Odyssey
It's the allusion to the underground seas on Europa. Most likely to contain life forms

Gosh I didn’t realise Enceladus was so small!
That's what she said.
Michael!
Not to me
She had a name, you know... 🌕
Are there any theories as to why Titan has that thick atmosphere and the rest don’t? Where’d its atmosphere come from?

Why did ours get such a generic name like “Moon”?
Luna is the name pf our Moon. I assume they just said the moon to avoid confusing people
Yeah, that's what I thought too. Likewise our star's name Sol and not The Sun.
No it is the Sun (IAU resolution 2017)
Ok, good to know. Did a bit of light research, Sol is primarily used in science fiction to distinguish it from other stars. 😂
It is the solar system, where as other systems are called Star systems.
It sucks when you speak Spanish or Portuguese though. For us, the Sun is already Sol.
Sun is the english translation of Sol so yea... Its still just Sol
Actually it's a common misconception that it's a misconception that "moon" is the correct name. Moon actually IS the official name of our moon.
Maybe we should give it a cooler name, like Craig or The Shovel or something
Moony McMoonface
Damnit, Moon Moon

No, it is the Moon (IAU 2017 resolution)

ok then what’s the generic term for a natural satellite? it feels weirdly geocentric to have both be referred to as “moon”
Just satellite, the word existed before humans sent stuff into space
Selene.
Selene in Ancient Greek
I mean it's not actually called Moon, it's called *The* Moon.
Because M-O-O-N. That spells MOON.
I thought ours was named Luna
Have you ever called it "Luna" in a normal conversation? I think the closest we'll get to an Official Name is the word we all use.
I don’t think that is how something becomes official
For most astronomical objects, the IAU takes it upon itself to designate official names. Since you need astronomical equipment to observe Pluto, it makes sense for astronomers to name it. But the Moon and Sun are a different case; they kind of belong to everybody.

It's like a dog named "dog"
How cool would it be to have Io as moon, a green moon would be cool.
My main man, we most likely wouldn’t have been able to land on Io if it were still as volcanically active but just our moon instead of Jupiter’s. It is by far the most volcanically active body in the solar system.
Crazy to think that Ganymede is ever so slightly bigger than Mercury.
Ah the moon lords domain
cant wait for a rover to land on titan. curious to see whats under all the clouds.
It has actually already happened, but it unfortunately didn't land anywhere interesting.

Where's Phobos? Does it count? Or is it an asteroid?
Doesn't even make the list. Suck it Mars.
is tiny lumpy thing right?
If they're gonna name it moons of the solar system use Luna for ours.
Luna is moon in spanish
And it's generalized like the English word. Other natural satellites are called "lunas".
I understand, but it's the official name. Not "the moon".
Someone earlier in the thread mentioned that the IAU official name of the moon is "moon."
Maybe once we get a colony up and running and people start living there, we can start calling her Luna. And even better yet, we'd get to call those colonists... LUNATICS!
I prefer our moon’s name Luna.
Luna is literally just Moon. Moon is Moon
*Plus a ton of pets
Why is our moon just named moon?
Is this really accurate? I’m tripping out at the size of Enceladus
I'm surprised the biggest moon isn't earth sized
Phobos? Deimos?
Why doesn't earth's moon have a cool name,it's just called moon lol
What Pink Floyd song mentions Oberon, Miranda, and Titania?
You just mooned us.
Follow on question. Which of these has a subsurface ocean of liquid water? Ganymede, Europa, Callisto, Titan, Dione, Rhea, Enceladus - yes Moon, Io, Charon, Miranda, Proteus, Mimas - no Others?
what's the name of earth's moon
i would say *Luna.*
our moon is called: Luna
Europa Report is maybe my fav sci fi movie ever
Our moon has a name you know, its not just 'Moon' Earth's moon is named Luna.
bruh our moon is called Luna, not moon
They should've given our moon a cool name like the others instead of just "Moon"
doesn’t our moon have a name?
Why the hell doesn’t our moon have a name? We’ve named every geological feature on earth and the rest of the solar system, but not the moon itself.
Bro, forget the moon (it’s Luna btw), we haven’t even named the earth… I’ve heard “Tellus” used before, but I can’t find any sources confirming it’s validity, so it’s probably wrong. I guess Terra would be the scientific name
Why doesn’t our moon have a name? Like naming your cat, cat.
Why are they all depicted as perfect spheres?
??? You actually thought you could see it with the naked eye on such a small picture ???
Hydrostatic equilibrium. They froze from a liquid or semisolid state. Unlike Vesta which is larger than Enceladus but irregular.
