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.

Why would Ptolemy not explain venus phases?
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 Galileo find in his scientific observations that convinced him that Ptolemy had been wrong?
When Galileo observed that there are satellites which orbit the planet Jupiter, this was clear evidence that not everything orbits the Earth.
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.
A fatal flaw with Ptolemy's model is its inability to predict the observed phases of?
the planets accurately. This is because Ptolemy's model relied on epicycles and deferents to explain the apparent retrograde motion of planets, which resulted in discrepancies with the observed phases over time. Copernicus later proposed a heliocentric model that offered a more accurate explanation for the phases of planets.
When did Galileo confirm the phases of Venus?
Galileo Galilei first recorded phases in Venus in 1610, and published his findings in 1613.

What phases of venus are predicted by the ptolemaic system?
The Ptolemaic system predicts that Venus goes through phases similar to the Moon, from crescent to full. This model was proposed by the ancient Greek astronomer Ptolemy and was used to explain the varying appearances of Venus in the sky as seen from Earth.

What are the phases of Venus's moons?
Venus has no moons.
Did Galileo Discover Venus's?
No. He discovered the phases of venus.
When do the phases of venus occur?
The phases of Venus occur as a result of the planet's position relative to Earth and the Sun. As Venus orbits the Sun inside Earth's orbit, it exhibits phases similar to the Moon. The phases range from crescent to full Venus and back again as viewed from Earth.
When did Galileo confirm the phases of Venus?
Galileo Galilei first recorded phases in Venus in 1610, and published his findings in 1613.
What is the significance of Galileo observation of the phases of Venus?
The phases of the planet Venus are the different variations of lighting seen on the planet's surface
In what way is Venus' similar to our moon?
Venus has phases like the moon
How many phases does Venus go through?
Venus goes through four main phases similar to the Moon: new, crescent, quarter, and full. These phases result from the varying positions of Venus in relation to the Earth and the Sun, affecting how much of the illuminated side of Venus is visible from Earth.
