How is the geocentric view different from the heliocentric view?

Answer 1

In astronomy, the geocentric model or the Ptolemaic worldview of the universe is the superseded theory that the Earth is the center of the universe and other objects go around it. Belief in this system was common in ancient Greece. It was embraced by both Aristotle and Ptolemy, and most Ancient Greek philosophers assumed that the Sun, Moon, stars, and naked eye planets circle the Earth. Similar ideas were held in ancient China.

Two common observations were believed to support the idea that the Earth is in the center of the Universe: The first observation is that the stars, sun, and planets appear to revolve around the Earth each day, with the stars circling around the pole and those stars nearer the equator rising and setting each day and circling back to their rising point.[2]; the second is the common sense perception that the Earth is solid and stable it is not moving-but is at rest. The geocentric model was usually combined with a spherical Earth by ancient Greek and medieval philosophers. It is not the same as the older flat Earth model implied in some mythology. The ancient Greeks believed that the motions of the planets were circular and not elliptical, a view that was not challenged in western culture before the 17th century. The geocentric model held sway into the early modern age; from the late 16th century onward it was gradually replaced by the heliocentric model of Copernicus, Galileo and Kepler. Today, geocentric cosmology survives as a literary element within alternate history and science fiction. By Edem Uboh(Lead City University,Ibadan.)

Answer 2

Heliocentric means "sun-centered" and puts the planets in an orbit around the sun. Geocentric is an ancient model, invented by Ptolemy, that means "earth-centered" and puts the Earth at the center of the universe with the sun and planets orbiting it. The geocentric model was based off religion and was proven wrong by Copernicus in the fifteenth century.

Answer 3

They differ in what or that they [each in turn] consider to be the Object around which all other celestial bodies revolve.

In the heliocentric view, the Sun is the centre.

In the geocentric view, the Earth is the centre.
