1 Background of Early Astronomers Looking Back

2 1. Ptolemy (87-150 AD) He thought He thought A. Earth was the center of the solar system (Geocentric view) B. Other planets revolved around Earth, but as they did, they also revolved around a central point

3 1. Ptolemy http://www.astronomynotes.com/history/s3.htm

4 2. Copernicus (1473-1543) He thought: He thought: A. The Sun was center of the solar system & Earth revolved it, Earth is tilted & rotates. (Heliocentric – sun centered view) (Heliocentric – sun centered view) B. Orbits were perfectly circular, Earth rotated, & its axis is tilted C. Known as the founder of modern astronomy

5 2. Copernicus http://www.cartage.org.lb/en/themes/sciences/Astronomy/Thestars/stellardistances/TheParallaxMethod/TheCopernicanModel/copernicus.gif

6 3. Brahe (1546-1601) He thought: He thought: A. Earth was center of the solar system, so the Sun revolved around it B. All other planets revolved around the Sun Geo-heliocentric view Geo-heliocentric view C. He tried to merge Ptolomy & Copernicus’ C. He tried to merge Ptolomy & Copernicus’ ideas ideas

7 3. Brahe http://www.answers.com/topic/tychonic-system

8 4. Kepler (1571-1630) A. An assistant to Brahe, but once he died, he used his data and recalculated to get the correct description B. He found: a. All Planets do revolve around the Sun b. Their orbits are elliptical

9 4. Kepler http://www-tc.pbs.org/wnet/hawking/universes/assets/images/u.kepler.jpg

10 5. Galileo (1565-1642) A. Used the 1 st telescopes to view the night sky in 1610. B. He found: a. Jupiter had 4 moons revolving around it, so Earth could not be the center of the universe. b. Saturn’s rings, sunspots C. He was arrested because his views went against the beliefs of the Church.

11 Assessment: Group Modeling Each person in group will be a different object (with a sign) Each person in group will be a different object (with a sign) Outside, teacher will call out an astronomer and group needs to show each objects movement Outside, teacher will call out an astronomer and group needs to show each objects movement Don’t forget, the same side of the Moon always faces Earth. Don’t forget, the same side of the Moon always faces Earth.
