The traditional model was that they moved in "epicycles", which is basically a point on a circle, which both rotates, and revolves around another circle.Since the planets actually move around the Sun in ellipses, this model is not entirely accurate.

What is the difference between the geocentric and heliocetric models of planetary motion?

Well, let's paint a happy little picture here. In the geocentric model, Earth is believed to be the center of the universe, with all other planets and the Sun revolving around it. On the other hand, in the heliocentric model, the Sun is at the center, and Earth and other planets orbit around it. Both models have their own beauty and history, showing us how our understanding of the cosmos has evolved over time.


What is the description of the solar system in which all the planets revolve around earth?

The concept that all planets revolve around Earth is known as the geocentric model. This idea was proposed by early astronomers before the heliocentric model, with Copernicus and Galileo helping to advance the understanding that Earth and other planets actually revolve around the Sun.


What is the difference between heliocentric and genoictric?

Heliocentric refers to a model where the Sun is at the center of the solar system, with other celestial bodies orbiting around it, while geocentric refers to a model where the Earth is at the center of the universe, with the Sun and planets orbiting around it. The heliocentric model was proposed by Copernicus in the 16th century, challenging the geocentric view that had been dominant for centuries.


2 models of the solar system?

Theres the Geocentric model, with earth at the centre and the planets and sun revolving around us. Then there is the Heliocentric model, with the sun at the centre and all of the planets including Earth revolving about it. The second model is the correct model, though for many years people assumed incorrectly that the Earth was at the centre of the universe.


What is a geocentric model of your solar system?

A Geocentric model places Earth at the center of the Universe, with all of the stars and planets revolving around it. The most famous such model is that of Ptolemy. It stood as the accepted model until Copernicus was proven right by Galileo and Kepler.

What is a description of the solar system in which all planets revolve arond the earth?

The Geocentric Theory, or The Geocentric Model, proposes that the Earth is the center of the Universe and all other objects orbit around it.


What does the geocentric model look like?

It is the theory in which the earth is the center of the universe and that all the planets revolve around it including the sun. this theory was developed by Aristotle.Geocentric theory basically stated that the Earth was at the center of the universe, and that the sun, moon, planets, and other heavenly bodies revolved around it. This theory was believed extensively during the middle ages.

What is the differnts between geocentric model and heliocentric model?

You should read a book and find out, don't always go the easy way out. Timmy Same- Both are models of the solar system and how the sun and planets are arranged. Different- Geocentric- revolves around the earth. Heliocentric- Planets (including Earth) revolve around the sun. your welcome.


In the geocentric model of the solar system earth is where?

In the geocentric model of the solar system, Earth is considered to be at the center with all other celestial bodies, including the sun, planets, and stars, orbiting around it. This model was widely believed in ancient times but was later replaced by the heliocentric model, which correctly places the sun at the center of the solar system.


Did Eudoxus believe in geocentric or heliocentric?

Eudoxus believed in geocentric that means the orbits of the planets go in a perfect circle


In a geocentric theory which body do the other planets orbit?

The other planets - and all other bodies - orbit the earth.


What is the major difference between the geocentric model in the heliocentric model?

The major difference between the geocentric and heliocentric models lies in the center of the solar system: the geocentric model places the Earth at the center, with the Sun and planets orbiting around it, while the heliocentric model positions the Sun at the center, with the Earth and other planets orbiting around it. The heliocentric model, proposed by Copernicus, is supported by observational evidence and eventually led to a better understanding of planetary motions, while the geocentric model was based on ancient beliefs and lacked empirical support.


What type of model is a heliocentric?

A heliocentric model is a model of the solar system where the Sun is at the center and the planets orbit around it. This is in contrast to the geocentric model, where Earth is considered to be the center of the universe.


What did the Copernicus universe suggest?

Copernicus suggested a heliocentric model of the universe. Meaning, the earth was the centre of the universe and other planets had to orbit around the earth. This model of the universe was against Ptolemy's model of a geocentric model; a stationary Earth at the centre of the universe.
