Question

What prediction was made of Venus to prove that it circled the Sun instead of the Earth?

Answer 1

Heliocentric Model

Step-by-step explanation:

The heliocentric model of the solar system developed by Copernicus predicted that all phases would be visible since the orbit of Venus around the Sun would cause its illuminated hemisphere to face the Earth when it was on the opposite side of the Sun and to face away from the Earth when it was on the Earth-side of the Sun.
