Yes because it allowed Venus to go behind the Sun (as seen from the Earth), thus allowing Venus to show the gibbous phase observed by Galileo. Tycho's model had the Moon and Sun orbiting the Earth, and the other five known planets orbiting the Sun. So it was a halfway house between the Ptolemaic system (completely geocentric) and the Copernican system (completely heliocentric). Tychos model was geocentric while correctly modelling Venus's phases. This was significant because it meant that Venus's phases could not be used as a 'proof' of Copernicus's heliocentric model, as attempted by Galileo. Eventually these three models were abandoned to the history books after Kepler's heliocentric system with elliptical orbits was accepted; because (a) it modelled the planets' positions more accurately and (b) it was consistent with the later discoveries of gravity and the laws of motion.
When Galileo observed that there are satellites which orbit the planet Jupiter, this was clear evidence that not everything orbits the Earth.
Well, Some of the astronomical things that he observed are: the phases of Venus. the craters on the Moon .Jupiter's orbiting moons
Gallieo Galilei first observed that Venus has phases. This is due, primarily, to the fact that Venus is closer to the Sun than the Earth is. In order to display phases, particularly crescent phases, the observed object must be closer to the Sun than the observer.
Galileo looked at the planet Jupiter and observed its 4 largest moons (which are still known as the Galilean moons, to this day).

Galileo discovered the sun is the center of the solar system, he improved the telescope, he proved that the moon has craters on it, he claimed Venus has phases, and he observed sun spots on the sun.

Galileo observed phases of Venus, which were only possible if Venus orbited the Sun and not Earth, supporting the heliocentric model of the solar system proposed by Copernicus. This observation was a key piece of evidence in favor of the heliocentric theory.
Well yes and no. The phases of the moon were understood well before Galileo --- however Galileo discovered the moons of Jupiter and no doubt their associated phases --- as well as the phases of Venus.
I think that it is because Tycho thought that the sun and the moon orbited Earth but the rest of the planets orbited the sun So this means that from our perspective if tycho was true then the phases of Venus would look different Its not a very technical answer sorry so it could do with improving
Galileo Galilei first recorded phases in Venus in 1610, and published his findings in 1613.
Galileo discovered the moons of Jupiter and observed the phases of Venus, providing evidence to support the heliocentric model of the solar system. Herschel discovered the planet Uranus and infrared radiation, expanding our understanding of the universe.
Galileo discovered the telescope, and phases of the moon
