Why was Galileo's telescopic discovery of the moon orbiting jupiter so important?

Answer 1

Galileo discovered Jupiter's moons which had not been seen before he turned his telescope on to Jupiter.

Galileo observed the four moons and deduced that they are in orbits around Jupiter. The significance of this, as Galileo realised, was that up until then everything in the universe was assumed to revolve around the Earth.

Galileo thought that this discovery added credibility to the new theory of the planets' movements among the stars, published by Copernicus in1543, which had the Sun at the centre with the six known planets revolving around it.
