Geocentric Simulation
There should be a functional simulation of a geocentric solar system in the different available simulations. And when I mean functional, I mean at least for the moon, earth, and the sun. However, my knowledge of astrophysics only goes so far so I totally realize that this might be too much to ask for.

that cant really work. i mean, you can maybe center the camera relitive to an earth-like body and have a star "orbiting" it, but that's only a visual trick of the reference frame.

the attractive force of gravity is proportional to the mass of an object. a less massive object is always pulled around by a more massive one.

then you have to look at the hill sphere. that's the region around a body where that body is gravitationally dominant. ignoring that the earth is well, well, within the sun's hill sphere, the earth's hill sphere is about 4x the earth-moon distance. at that distance, the earth would be deep under the surface of the sun.

If you want everything to be of the correct mass then you couldn't do it as as Tarn said you cant have a larger body orbit a much smaller one. If you wanted to cheat you could change the masses of everything...

It exists. There's this button called "Set as Trail Center"

that's just changing the camera reference frame. you'll notice that your centered target still has speed, yes?

it'll look like the smaller is orbiting the larger, but that's all. the actual orbits will still be heliocentric.

pulsar and earth-earth has less mass, so it will orbit around pulsar
