What is the difference between a geocentric snd heliocentric model of the solar system?

Answer 1

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.

Answer 2

A Heliocentric model places the Sun at the centre with the planets in orbit around it, while a Geocentric model places the Earth at the center with the Sun and the rest of the planets in orbit around it.

Answer 3

One is incorrect and the other is correct

• The Heliocentric model or Copernican model it places the sun as the center of the Solar system, with all the other planets revolving around it, This is correct.

• The Geocentric Model place the earth as the center of the solar system, with all the other planets and the sun rotating around it. This is incorrect.

It's whether the Sun or the Earth is at the centre. Early models had the Earth at the centre (geocentric) and a system of circles and epicycles was used to explain the movement of the planets because the early astronomers knew from observations that simple circular orbits did not fit the observations.

Copernicus produced an alternative model with the Sun at the centre (heliocentric), but it was a model that still used circles and epicycles.

Kepler assumed the Sun was at the centre and also used superior observations made by Tycho Brahe to show that the planets move in elliptical orbits.

Newtons discoveries led to a better understanding of what causes the orbits to be elliptical and now the heliocentric system with elliptical orbits is generally accepted.

<<>> All the models predicted the planets' positions reasonably accurately, but Copernicus discovered that the planets' paths were geometrically simpler if the Sun was placed at the centre. Until Newton came along in the late 1600s there was no way of knowing definitely which model was the correct one.

Answer 4

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.

Answer 5

A heliocentric model of the solar system is where the sun is at the centre (Helios means sun in Greek). We know know this to be the correct model. The geocentric model is where the earth is at the centre of the solar system and the sun and all planets are in orbit around the earth. This is how people thought it was many years ago in the middle ages and earlier, but we now know that this is not the true model.

Answer 6

The Geocentric model of the solar system proposed that the Earth was at the centre of the system (and universe), while the sun and planets revolved around the Earth. We now know this not to be true and that the sun is at the centre of the solar system (Heliocentric).

Answer 7

The heliocentric model places the sun at the center of the solar system where the gercentric model places the Earth at the center.
