Question

What did the original heliocentric model state about our solar system? What was different from a geocentric model? What was the same?

a) The heliocentric model stated that Earth orbits the Sun, which was different from the geocentric model where the Earth was at the center. The same was the circular motion of planets.
b) The heliocentric model stated that the Moon orbits the Earth, which was the same as the geocentric model. The difference was that the Sun orbits the Moon.
c) The heliocentric model stated that Earth is stationary at the center of the solar system, just like the geocentric model. The difference was the elliptical orbits of planets.
d) The heliocentric model stated that all planets orbit the Sun, which was different from the geocentric model. The same was the concept of epicycles.

Answer 1

The original heliocentric model stated that Earth orbits the Sun, different from the geocentric model where Earth was at the center. Both models shared the concept of circular motion of planets. The heliocentric model also stated that all planets orbit the Sun.

Step-by-step explanation:

The original heliocentric model stated that Earth orbits the Sun, which was different from the geocentric model where the Earth was at the center. However, both models shared the concept of circular motion of planets. The heliocentric model also stated that all planets orbit the Sun, which was different from the geocentric model. The concept of epicycles was the same in both models
