How did Galileo's observations of Jupiter and Venus support Copernicus's model?

1 Answer


Before Copernicus most people were thinking that the Earth is at center of universe.


In 1609 Galileo observed sky through his home made telescope.
He found 4 moons orbiting Jupiter..It was a proof that bodies are orbiting other planets Not earth alone.
He found the crescent shape of Venus through his telescope.This could happen only if Sun is at center,.
