Solar System Models

Heliocentric model positions the SUN at the center with Earth and planets orbiting around it.
Geocentric model places the EARTH at the center, where the sun, moon, and planets revolve around it.

Greek Terminology

"Helio-" comes from Greek, meaning "sun."
"Geo-" originates from Greek, meaning "earth."

Key Figures in Astronomy

Galileo Galilei advocated for the Heliocentric Model and is renowned for discovering Jupiter's four moons.
Ptolemy developed the Geocentric Model and provided explanations for the observed movements in the sky.
Johannes Kepler established that planetary orbits are shaped as ellipses, not perfect circles.

Notable Scientists

Ptolemy is the scientist associated with the belief in the Geocentric model.
Three key proponents of the Heliocentric model include Nicolaus Copernicus, Johannes Kepler, and Galileo Galilei.

Concepts and Definitions

An ellipse is an oval shape representing the orbit of each planet around the sun.
