Johannes Kepler
The greatest inaccuracy in Copernicus' model of the solar system was that he still believed that planets moved in perfect circles, when in fact they move in ellipses. This led to inaccuracies in predicting planetary positions.
Ptolemy
Uranus is in the heliocentric system like all the other planets. The geocentric system is now only of interest historically. It wasn't correct.
The phases of Venus are well supported by the heliocentric system, but they are also supported very well by the previous geocentric system. All you need for Venus to have phases is that Venus should pass between Earth and Sun. That happens in both the heliocentric system and the geocentric system.
Heliocentrism is the astronomical model in which the earth and planets revolve around the Sun in the center of the Solar System. Heliocentric is the adjective describing this system.
One of the discoveries that led to the modern view of the Solar System was that the orbits of the planets were ellipses. This was one of the key contributions from Johannes Kepler's laws of planetary motion, which replaced the earlier belief that planetary orbits were perfect circles.
