Ptolemy and copernicus were early astronomers Ptolemy believed that earth was the center of the solar system and copernicus believed that the sun was the center of the solar system which model below would the astronomers most likely use to support their briefs

Ptolemy would most likely use the geocentric model to support his belief that Earth is the center of the solar system. This model depicts Earth as a stationary object at the center, with all other celestial bodies, including the Sun, orbiting around it.

Copernicus, on the other hand, would most likely use the heliocentric model to support his belief that the Sun is the center of the solar system. This model illustrates the Sun as the central object, with Earth and other planets revolving around it in circular or elliptical orbits.

Ptolemy, who believed that the Earth was the center of the solar system, would have most likely used the geocentric model to support his beliefs. The geocentric model suggests that all celestial bodies, including the sun, revolve around the Earth.

On the other hand, Copernicus, who believed that the Sun was the center of the solar system, would have most likely used the heliocentric model to support his beliefs. The heliocentric model suggests that all celestial bodies, including the Earth, revolve around the Sun.

So, Ptolemy would have supported the geocentric model, and Copernicus would have supported the heliocentric model.

To determine which model would be most likely used by Ptolemy and Copernicus to support their beliefs, we need to understand their viewpoints and compare them.

Ptolemy, an astronomer from ancient Greece, developed a geocentric model of the solar system. According to this model, Ptolemy believed that the Earth was at the center of the solar system, and the Moon, Sun, planets, and stars revolved around it. Ptolemy's model was widely accepted for many centuries due to its accuracy in predicting celestial events.

On the other hand, Nicolaus Copernicus, a Polish astronomer, formulated a heliocentric model of the solar system. In Copernicus's model, the Sun was at the center of the solar system, and the Earth, along with other planets, orbited around it. Copernicus's heliocentric model challenged the prevailing geocentric view and laid the foundation for modern astronomy.

Considering the beliefs and models proposed by Ptolemy and Copernicus, it is clear that Ptolemy would support the geocentric model, while Copernicus would advocate for the heliocentric model.

Therefore, Ptolemy would most likely use the geocentric model to support his beliefs, whereas Copernicus would support the heliocentric model in his arguments.
