Slightly outside the sun. The comment above was talking about the Earth being center as a judgement call, which is a wildly different idea.

If all you care about is measurements/predictions relative to Earth, then it makes no sense to transform everything into Sol-centric frame, do the math there, and then untransform results back to Earth-centric frame.
Put another way, there's a reason we use latitude/longitude for terrestrial positioning, instead of Cartesian coordinates with Sol being at (0, 0, 0). For one, it keeps the math time-invariant.
