Ptolemy did not explain Venus phases in his geocentric model because he believed that Venus, like all other planets, moved around the Earth in perfect circles and did not exhibit phases like the Moon. His model could not account for the varying phases of Venus because it was based on circular motion and did not include elliptical orbits or the correct understanding of planetary motion.

What did Ptolemy think about the phases of Venus'?
Ptolemy believed that Venus, like other planets in his geocentric model of the universe, exhibited phases due to its position relative to the Earth and the Sun. He thought that the varying shapes of Venus as seen from Earth were caused by the changing angles between the three celestial bodies.
What phases of Venus should have been observed according to Ptolemy?
According to Ptolemy's geocentric model, Venus would exhibit two phases: a crescent phase and a full phase. He believed that Venus orbits the Earth and thus would appear as a crescent when it is positioned between the Earth and the Sun, and as a full phase when it is on the opposite side of the Earth from the Sun. However, Ptolemy's model could not account for the full range of phases observed by later astronomers, such as Galileo, who demonstrated that Venus also exhibits gibbous and new phases, supporting the heliocentric model.
Can Tycho's model explain the phases of venus as observed by Galileo?
No, Tycho's model cannot explain the phases of Venus observed by Galileo. Tycho's model proposed an Earth-centric system with the planets revolving around the Sun, which would not account for the varying phases of Venus. Galileo's observations of Venus' phases provided evidence in support of the heliocentric model proposed by Copernicus.
Galileo's observation of the phases of Venus supported Ptolemy's epicycles?
Galileo's telescopic observations of the 4 large moons of Jupiter and the phases of Venus helped support the heliocentric model of the solar system developed by Copernicus. 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. In contrast, the geocentric model of Ptolemy predicted that only crescent and new phases would be seen since Venus was thought to remain between the Sun and Earth during its orbit around the Earth. Galileo's observations of the phases of Venus proved that it orbited the Sun and lent support to (but did not prove) the heliocentric model.
Why doesnt tycho's model of the universe explain the phases of venus that Galileo observed?
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

What planets are seen in phases like the moon?
Both Mercury and Venus, being closer to the sun than us, will show phases. When Venus is at is brightest it is generally just a bit over half full. If you were on Mars, you would note phases on earth.
What planet is seen as the same phrases like the moon?
There are none. The planet Venus is often seen in its gibbous and crescent phases, but never appears to be full; when it would be, Venus is hidden behind the Sun. And Venus only appears in the "new" phase twice per century, during the "transits of Venus". The planets Mars, Jupiter and Saturn appear in the gibbous and full phases, but never in the crescent or new phases.

What did the phases of venus suggest about the motion of all planets?
The phases of Venus, observed by Galileo, provided crucial evidence for the heliocentric model of the solar system, which posits that planets orbit the Sun. These phases, resembling the phases of the Moon, indicated that Venus orbits the Sun and not the Earth, as they would not occur if Venus were to revolve around the Earth. This observation supported the idea that all planets, including Earth, move in relation to the Sun, fundamentally changing our understanding of the cosmos. Ultimately, it reinforced the notion that the Sun is at the center of our solar system, with planets, including Earth, orbiting around it.
How did Galileo disprove the Geocentric theory of the solar system?
Galileo's observations of the phases of Venus proved that it orbited the Sun and lent support to (but did not prove) the heliocentric model.Galileo saw the four largest moons of Jupiter in orbit around the planet, proving that the Ptolemaic system was not simpler - the solar system was not geocentric (the planets and the sun did not orbit around the earth).As far as the observations of Venus go, Galileo saw that Venus displayed phases very much like our moon. Now, according to the Ptolemaic system, Venus could only display a crescent phase because its epicycle put it always in between Earth and the sun. The Copernican system put everything rotating around the sun, and in this way it explained the phases of Venus.Think of it this way, if Venus is always in between the sun and the earth, how can we ever see it completely lit up, like a full moon? The sun is always on the other side of it, so Venus must at some point go on the other side of the sun.
Does Mars go through phases similar to the moon?
Only partly. We never see Mars in a crescent or new phase, just the full and gibbous phases. That's because Mars is farther away from the Sun than the Earth is, so we never see it "inside" our orbit. On the other hand, we see the crescent and gibbous phases of the planet Venus, but never the full or new phases, because when Venus would be "new", it's too close to the Sun to be observed - and when Venus would be "full", it's on the other side of the Sun, and not visible!
Which observations of Galileo refuted Ptolemy's epicycles?
Using his telescope, Galileo observed Jupiter over a period of months. He easily noticed the 4 largest moons. Which you can remember using this simple pneumonic device. I. E.at G.reen C.atterpillars Io, Europoa, Ganeimyde, and Callisto Anyway, he observed these over a period of month, and sketched their movements every week or so, and eventually began to notice that they would disappear for a day or two, and then reappear on the other side of Jupiter. Logically they must have been orbiting around Jupiter. This contradicted the Ptolemic model in which all objects in space orbited around the earth.
How did the Renaissance rediscovery of the work Egyptian astronomer ptolemy help start the scientific revolution?
The Scientific Revolution started because current scientific theories would not explain what the Egyptian astronomer Ptolemy found. This lead to the advancement of a Scientific Revolution to study of his ideas.
