What was galileos thepry of the solar system?

Answer 1

We'll never know. But it may be worth noting that Galileo supported and played a major role in the theory concerning the heliocentric theory, or the belief that the Sun was at the center of the Solar System.

Answer 2

Galileo Galilei's theory of the solar system was largely based on the heliocentric model proposed by Copernicus, with the sun at the center instead of the Earth. Galileo's observations and use of the telescope provided evidence to support this model, ultimately leading to a better understanding of the structure of our solar system.
