Helio Centric Model

We see high resolution snapshots of earth proving earth is spherical. However to prove helio centgricity we must take angles of planets and make some transforms whether on a satellite telescope or earth observatory with sky maps. We can make out the mass of earth with density being near 2e3 kg/m^3 from sinking of stone. Then find R through acceleration due to gravity or sky trip time and speed. This way we get mass of earth to be 5e24 kg and mass of sun can be calculated as less than chandrashekar limit for degenerate gas. This way mass of earth is 2e30 kg clearly sun the heavier object is at center and Trev=365 days proves the distance to sun.
