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 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.
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.

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.
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
When did Galileo confirm the phases of Venus?
Galileo Galilei first recorded phases in Venus in 1610, and published his findings in 1613.
In what way is Venus' similar to our moon?
Venus has phases like the moon
