Don’t forget that Celestia says “where on Earth” in one episode as well. I think it’s fair to say Equestria resides on planet Earth.

Let’s just all agree that until they officially name the planet, let’s assume it’s a parallel Earth different from Equestria Girls and ours and the infinite amount of others in a huge multiverse where there’s just no humans.

The two most specific uses of “Earth” that do not seem to refer to soil I could find are Pinkie in Hearth’s Warming Eve, and Twilight in Applebuck Season. I mean, would anyone ever say “what on dirt are you doing?”

Pretty sure there was one in lesson zero too, nothing new

@Vivace
 
Probably only Equestria would use them, if there were any - time zones as we know them only came about when railways started getting popular.

@Vivace  
They are divided equally so they actually make sense

Now here’s a question: how do time zones work?

AJ’s character wanted to name the new land Earth in that episode.
 
The world is the only official description of their world.
 
Thi is pointless

@MadVillain  
are you sure they were talking about the planet as a whole? give me a direct quote… because i’m sticking with equus until we have undoubtable proof like when a character says something involving the words “planet” and insert planet name in the same sentence… because we will only know for sure when the name is undoubtedly in the crystal clear context of the entire planet
 
edit: I looked it up and pinkie/chancellor puddinghead implied the name of the planet was earth but then again anything pinkie says should be taken dubiously at best because of pinkie being a serial 4th wall breaker(possibly referring to OUR earth instead of their planet) and also being a tiny bit insane

@ma3a  
What? We have heard it mentioned before what they call their planet, I’ve literately been saying that since my first comment. They’ve named the planet Earth since the Hearths Warming Eve episode in Season 2.
 
 
And imo even if there wasn’t an actual name Equss is terrible.

also by “official cannon name” I mean the ponies referring to the planet using a very specific name with no dispute about it… or for Hasbro or the show writers to make an actual mlp globe depicting the planet name and it’s true geography because at this point we can only assume it’s an earth sized planet we only know what the equestria mainland looks like we dont even know how BIG equestria is… is it a peninsula or a continent? we dont know because we dont have enough information and we have too many inconsistent maps… hell we dont even know what the other continents on the planet look like… or it’s name so until we get an actual name or their planet I am calling it equus

@MadVillain  
see comment that mentions earth meaning dirt… and honestly we DONT know what they call their planet because we have never heard it mentioned as a whole before… some of us fans just call it equus because of it’s dominant race and because it has a nice ring to it and also tbh as a bit of placeholder for when we get an official cannon name for their planet

@ma3a  
We don’t know that most creatures on the planet are equines though, and the country the equines inhabit is already named after their species, so the planet which we don’t even know if they named, being also named pretty much the exact thing is multiple layers of redundant.
 
 
@Background Pony #669C  
But Ponies calling their world Earth implies it’s named Earth though.

@onil innarin  
because they have never referred to their world on a planetary scale it’s always just a nation or at most a continent we have yet to see equus as a whole planet(globes dont count we need to see it from space and hear it named)

@ma3a  
Also, never has the word ‘equus’ ever appeared in FiM

oh and ponies also obviously have VASTLY diferent naming conventions from humans(ahhem case in point insert pony name here) almost every pony name is two words and honestly it seems like they have the same naming conventions as the forerunners from halo(guilty spark, mendicant bias, penitent tangent, abject testament) tbh earth’s true name is Terra and the moon’s true name is Luna so humans are actually called terrans… but ultimately the naming of a planet is up to it’s inhabitants

@ma3a  
I mean, why isn’t our planet named Homo because of the most dominant species, homo sapiens?

@Background Pony #91BA
 
I once saw a theory that holds that their planet is in a unstable orbit _{(probably Discord’s doing)} that would eventually either plunge the planet into its star, or throw it out of its system, without the unicorns’, and later, Celestia’s intervention, and the ‘raising the sun’ thing is a very simplified explanation/figure of speech.

@MadVillain  
think about it most of the creatures on the planet have generally equine body types so the inhabitants would name it equus in reference to the genus of THE most dominant creature on the planet “equus caballus” or common ponies… as for it being called earth there are a few theories floating around that equus is earth just tens of thousands of years in the future after mankind destroyed itself, the eymology of “earth pony” would still be the same as the pony archeologists would have been able to dig up(literally) information about the past inhabitants of the planet…
 
that theory actually has support in the show when you see various characters wearing helmets… maud pie once wore a russian pickelhaube helmet which had the spike prior to world war 1  
spike once wore an M1 american army helmet which was used in wars from ww2 to the falklands war… granny smith wore one too.  
you see human socks sometimes in the show… usually in garbage cans.  
although even better evidence to support this is that rainbow dash named her pet turtle “tank” and also earlier in the same episode says and i quote “i want a pet thats fast as a bullet to catch up with me” obviously they know of humanity’s machines of war and have salvaged a few artifacts… also in a more recent epiode scootaloo mentions “a 2 stage liquid fuel rocket” they obviously know of semi complex rocketry
 
oh no… I have gone on a tangent again haven’t I?

@MadVillain  
The word earth in earth pony probably only means soil, as they have a lot to do with soil

Earth Ponies, Do not imply there world is also Called Earth.
 
Earth means Ground

@onil innarin  
Yeah they even say it’s round all the way back in Hearths Warming Eve. Also, you know, Earth Ponies. No one calls them Equss Ponies.

@FoldabotZ  
Equestria is a continent.
