Galileo’s observations of Jupiter’s moons helped prove:

**b. Heliocentrism**

His discoveries showed that not all celestial bodies revolve around the Earth, as previously thought in the geocentric model. Instead, he observed that Jupiter had moons orbiting it, which provided strong evidence for the heliocentric model proposed by Copernicus, where planets (including Earth) orbit the Sun.
