So how do you prevent lag on something as large as an artificial planet?

It's more of a drastic reduction in lag than total prevention. Unlike the current dodecahedron planets, my planet is one single entity. This reduces the number of overlapping collision check boxes. Also, I have less overall blocks than current planets.

Is it hollow, or it has less blocks because it is smaller?

Yes...

I'm going to post some thumbnails of the planet's core on my shipyard thread along with its specs. That will give a better idea of what I'm working with.
