What observation provided the empirical proof that the Earth is moving in an annual circuit around the Sun?
Answer
Precise measurement of stellar parallax
The revolution of the Earth was empirically proven through the precise measurement of stellar parallax—the apparent shift of nearby stars against distant background stars as the Earth moves across its orbit.
