True and that is mercury

Wait the sun itself its to big it would likely go in different direction of the mlp solar system

Could they even generate enough energy to make such a venture worthwhile? And even if they could, for how long would such a thing be sustainable? And that’s not even touching the economics of producing that energy for such a thing. I just think that there’s too many factors that would stack against the idea of a global scale hologram.

Well, everything is understandable here, the laws of physics in the pony world work on completely different principles. For example, telekinesis there is a natural force, while in our world it is non-existent magic.
I wonder how the universe works in the pony world, black holes, quasaurs, pulsars, etc.

That’s not how the sun orbits around its barycentre! Think of the sun as the hand that is spinning around while gripping one nunchuck and twirling around another nunchuck.

Okay, but what if Equestria is a rogue planet with an advanced holographic filter over the atmosphere to simulate day and night?

Hmm  

We need a tag for “astronomy in the comments”.

Bringing human logic to a magical reality filled with adorable talking equines and many other magical and mythical creatures is purely ineffective, but I can understand trying to make sense out of it.

Now all that’s left is to revolve the other planets around the earth/pony planet and use the educational institutions to indoctrinate the younger generations with the belief in a terran-centric solar system.

The sun and moon would need to stay in exactly the same relative positions in that case.
 
Equestria would need to constantly be in between the sun and moon (all three in a straight line), which would be impossible with our current theory of gravity, because an object in a further orbit would take longer to complete a cycle than an object in a nearer orbit.
 
I could imagine it working if the Princess’ magic was used to “speed up” the moon in its orbit so it retained the same orbital period as Equestria. That way Equestria would always be between them (even though it would make the moon a planet rather than a moon).
 
Still, if that was how it worked then the rotation of Equestria would cause the moon to always appear at night, directly opposite from the sun.
 
It wouldn’t have to be a geocentric model, it’d just require the moon to break physics a little.

Fuckin’ solar system, how does it work?

wAIT. WHAT IF. When they “raise the sun” and “raise the moon” they just rotate all of equestria (earth) with their magic.  

Not necessarily. Depending on the perspective on where you determine the fixed point to be, the whole solar system could rotate around the earth. If the entire solar system of local was the moon, Equestria’s planet, and the sun, it still works.

That dark grey planet is not having a good time.

Because this show is based on reality.

this makes only so much sense
