Why can't/couldn't the Earth be at the center of the Solar System?

Question

So, it is about Galileo and Ptolemy. Can you please explain why it couldn't be at the center of the Solar System. I have an idea, but I'm not sure. Thanks. Much appreciated. =]

Answer 1

In simpler terms, for the earth to be the center of the solar system, then all of the planets would have to relvolve around the earth. Many centuries ago, scientists did not have powerful enough telescopes and thought this was true. Now, we have been able to plot the trajectories of all of the planets and have found that all of them relvolve around the sun.

Hope this helps

Answer 2

Observations about planetary motions and satelite motions around planets are best explained by a heliocentric model of the solar system.
For instance, Venus goes through phases like our Moon.
Planets such as Mars that we can see from Earth will travel in one direction, then reverse and take on a retrograde motion. Such motions are best explained by the model that indicates Mars is traveling around the Sun and not around the earth.
Current space exploration, involving the sending of expeditions to the planets, proves the heliocentric model of the solar system.
A non-Copernican model is very complex and requires a huge amount of weird explanations to account for these planetary retrograde motions. The Copernican model (that is, the heliocentric, or sun-centered) is a much simpler, more elegant explanation. And when two models compete, it is usually the simpler one that prevails. (This principle of simple explanations prevailing over complex ones is known as Occam's razor.)

Answer 3

I does not have the amount of gravity the sun has.

First the sun was formed.

Then Earth and the other planets were formed later. By left over matter and gravity.
