In which model of the solar system does venus show a full range of phases from full to new geocentric or heliocentric?
The answer is - both. That is because Tycho Brahe had a geocentric theory that explained the full range of phases for Venus, but also the theories of Copernicus and Kepler both explained the phases of Venus.
The only theory which did not explain the full range of phases was the old Ptolemaic theory (Historikeren 16-07-2015).
What else can I help you with?
The heliocentric system gained support when galieo observed that?
the phases of Venus could only be explained by it orbiting the Sun, not Earth as in the geocentric model. This observation provided evidence that supported the heliocentric system proposed by Copernicus.
Who challenged the geocentric model of the solar system?
One of the key figures who challenged the geocentric model of the solar system was Nicolaus Copernicus, who proposed a heliocentric model with the Sun at the center and the planets, including Earth, orbiting around it. This heliocentric model eventually gained acceptance and revolutionized our understanding of the solar system.
Why did Galileo progress from the geocentric model to the heliocentric model?
Galileo progressed from the geocentric model to the heliocentric model due to his observations through the telescope, which revealed phenomena inconsistent with the Earth-centered view. He discovered the moons of Jupiter, demonstrating that not all celestial bodies orbit the Earth, and observed the phases of Venus, which supported the heliocentric theory proposed by Copernicus. These findings, along with his commitment to empirical evidence and scientific inquiry, led him to advocate for the heliocentric model as a more accurate representation of the solar system.
Which observer cannot be explained by a geocentric model?
The observer who cannot be explained by a geocentric model is one who sees the phases of Venus. In a geocentric model, Venus would always be positioned between the Earth and the Sun, preventing it from showing a full range of phases like those observed. The heliocentric model, which places the Sun at the center, accurately accounts for these phases as Venus orbits the Sun and can be positioned at varying angles relative to the Earth and Sun. This discrepancy was one of the key pieces of evidence that led to the acceptance of the heliocentric model.
What is the difference between geocentric and heliocentric?
Geocentric understanding places the Earth at the center of the solar system or universe (depending on what is being discussed, and when) A Heliocentric understanding places the sun at the center of the solar system, or universe.
Why has the heliocentric model been replaced with the geocentric model?
The heliocentric model is the one that replaces the geocentric model because the heliocentric model better described the solar system.
The heliocentric system gained support when galieo observed that?
the phases of Venus could only be explained by it orbiting the Sun, not Earth as in the geocentric model. This observation provided evidence that supported the heliocentric system proposed by Copernicus.
What are the geocentric and heliocentric theories of the universe?
The Geocentric or Ptolemaic Model put the earth at the center of the Universe. The Heliocentric Model postulated by Copernicus and, before him, Aristarchus, places the Sun at the center of the Solar System. Galileo's observations proved the validity of the Heliocentric Model.
Who challenged the geocentric model of the solar system?
One of the key figures who challenged the geocentric model of the solar system was Nicolaus Copernicus, who proposed a heliocentric model with the Sun at the center and the planets, including Earth, orbiting around it. This heliocentric model eventually gained acceptance and revolutionized our understanding of the solar system.
What is the difference betwen a heliocentric model of the solar system then a geocentric model?
Heliocentric means the sun is the center - everything goes around it. Geocentric means the Earth is the center and everything goes around us.

What does the geocentric model of the solar system does not explain?
The geocentric model of the solar system does not explain the apparent retrograde motion of planets, where they seem to move backward in their orbits. It also fails to account for the varying brightness and size of planets as observed from Earth. Additionally, the geocentric model struggles to provide a coherent explanation for the phases of Venus and the observations of distant celestial bodies, which are more accurately described by the heliocentric model.
Why does the geocentric system use epicycles when the heliocentric does not?
The geocentric system uses epicycles in order to create a model in which the earth is in the center of the solar system and the planets and sun look the way they actually look from the earth with the naked eye. The idea of epicycles was added by Ptolemy because without them his model was not consistent with what the ancients recorded about the position of the planets, the sun and the moon. It was important that the model be consistent with observation since the model was used for navigation and land travel. Once the telescope came into being it was evident that the geocentric model (which included the epicycles) was not consistent with was now observable in the sky, such as the way that Venus looked at different times of years (the phases of Venus). Therefore the geocentric model was abandoned for the heliocentric model. The heliocentric model's predicted movements that were closer to what was observable with the new technology. The heliocentric model does not "need" epicycles, in fact they would lead to false predictions inconsistent with what was observable.
Which model of the solar system has Earth at the center of the revolving planets and stars?
The geocentric model places Earth at the center of the solar system, with planets and stars revolving around it. This model was widely accepted until the heliocentric model, which has the Sun at the center, was proposed by Copernicus in the 16th century.
What is the difference between a geocentric model and heliocentric model of the solar system?
Heliocentric was thought to believe that the sun was at the center of the solar system and that the planets revolved around the Sun. Geocentric was thought to believe that the earth was the center of the solar system and that the planets revolved around the earth. We now know that our solar system is centered around the sun and is heliocentric.
