1578 -Tycho Brahe first sketches “Tychonic system” of the solar system

So to sum up the Earth alone is fundamentally at rest in the Tychonic system. The modification of this theory in comparison to its predecessors is that this was able to explain the variations in phases of venus. The Tychonic system is useful for astronomers today as an observational perspective since the Earth is our observing platform.
