Back

The Heliocentric model is a representation of the solar system where the Sun is at the center, and the planets, including Earth, orbit around it.

What scientific instrument did Galileo use to support the Heliocentric theory?

Back

Galileo used the telescope to observe celestial bodies, providing evidence for the Heliocentric model.

Front

What is the primary difference between the Geocentric and Heliocentric models?

Front

What is retrograde motion, and how does it relate to the Geocentric model?

Back

Retrograde motion is the apparent backward movement of planets in the sky, which was difficult to explain in the Geocentric model.

Front

How did Kepler contribute to the understanding of planetary motion?

Back

Johannes Kepler formulated the laws of planetary motion, which described the elliptical orbits of planets around the Sun.
