Answer

Brief Explanation:

Galileo observed the phases of Venus, which could only be explained if Venus orbited the Sun. This supported the heliocentric model where planets orbit the Sun. The elliptical orbits were discovered by Kepler, Earth's rotation causing the Sun - rise is a different concept, and the speed - distance relationship in orbits was also part of Kepler's laws.

Answer:

Venus has phases.
