Answer

Answer:

Venus has phases.

Brief Explanations:

Galileo observed Venus's phases, which supported the heliocentric model where planets orbit the Sun. Just as the Moon has phases due to its position relative to the Earth - Sun system, Venus having phases implies it orbits the Sun. The other statements were not Galileo's discoveries for this purpose. Kepler discovered that the orbits of the planets are elliptical. The idea about Earth's rotation causing the Sun to rise is a basic fact about Earth's rotation, not a discovery by Galileo to support heliocentrism. The relationship between a planet's speed and its distance from the Sun was also not Galileo's discovery for this specific support of heliocentrism.
