Question
What celestial body did Galileo observe, leading to evidence that supported the heliocentric model?MarsVenusJupiterSaturn
Solution 1
Galileo observed the celestial body Jupiter, which led to evidence supporting the heliocentric model. He discovered four of Jupiter's moons and noted that they were orbiting the planet, which contradicted the then-dominant geocentric model that everything orbited the Earth. This observation was a key piece of evidence in favor of the heliocentric model, where the sun is at the center of the solar system.
Solution 2
Galileo observed Jupiter. His observations of the four largest moons of Jupiter, now known as the Galilean moons, showed that these moons were orbiting Jupiter and not the Earth. This was a significant piece of evidence supporting the heliocentric model, which posits that the Earth and other planets revolve around the Sun.
