Geocentric coordinates are easily observable; just look at the sunrise and sunset. And if you zoom out even more and look at the galaxy, heliocentric coordinates become unreasonable.

And at the speed at which the solar system is orbiting the galaxy, I don't know that it would even look much like like the planets are orbiting the sun.

In fact the planets aren't orbiting the sun. They're orbiting the galactic center, and the sun just happens to disturb their orbits a bit: https://youtu.be/0jHsq36_NTU?si=VbRsJ_SyA7JK4TD8&t=53

Does it mean we are surfing our galaxy? I mean we are not in the same exact location any second-lapsed?
