9 Earth Moon Mercury Venus Sun Mars Jupiter Saturn

10 Claudius Ptolemy 150 Almagest

11 Misconception Ptolemy invented the Earth-centered solar system.

12 Misconception Ptolemy invented the Earth-centered solar system. Ptolemy organized and systematized the Earth-centered solar system based on ideas that had been developed over about 600 years.

15 Your Parents Solar System

16 Nicholas Copernicus 1543 On the Revolutions of Heavenly Spheres

17 Misconception Copernicus delayed publishing because he feared criticism from religious leaders.

18 Misconception Copernicus delayed publishing because he feared criticism from religious leaders. Copernicus delayed publishing (in part) because he feared criticism from scientists.

19 Earth Moon Mercury Venus Sun Mars Jupiter Saturn

20 Sun Mercury Venus Earth / Moon Mars Jupiter Saturn

21 Misconception Copernicus Sun-centered solar system was quickly accepted because it was much simpler and more accurate.

22 Misconception Copernicus Sun-centered solar system was quickly accepted because it was much simpler and more accurate. Copernicus Sun-centered solar system was just as complex as Ptolemy s Earth-centered solar system, and provided no more accuracy in its predictions.

23 Galileo 1609 Use of telescope for astronomy 1632 Trial by the Inquisiton

24 Misconception Galileo invented the telescope and was the first to use it for astronomy.

25 Misconception Galileo invented the telescope and was the first to use it for astronomy. Galileo was one of several folks who improved the spyglass so that it could be used for astronomy.

26

27 Misconception Galileo proved that Copernicus Suncentered solar system was correct.

28 Misconception Galileo proved that Copernicus Suncentered solar system was correct. Galileo tried to prove Copernicus Suncentered solar system, but his arguments were wrong.

29 Tycho Brahe Johannes Kepler

30 Misconception Astronomers embraced the Suncentered solar system because it is philosophically simpler.

31 Misconception Astronomers embraced the Suncentered solar system because it is philosophically simpler. Astronomers embraced the Suncentered solar system only when it could provide better predictions.

32 Isaac Newton 1687 Principia

33 William Herschel 1781 Discovery of Uranus

34 1801 Planet Ceres (Piazzi)

35 1801 Planet Ceres (Piazzi) 1802 Planet Pallas (Olbers) 1804 Planet Juno (Harding) 1807 Planet Vesta (Olbers) 1845 Planet Astraea (Hencke)

36 Urbain Le Verrier & John Couch Adams 1846 Prediction and discovery of Neptune

37 Rocky Planets Giant Planets

39 Misconception You can t just demote a planet!

40 Misconception You can t just demote a planet! In the mid-1800 s, astronomers demoted the many planets between Mars and Jupiter to be asteroids.

41 Clyde Tombaugh 1930 Discovery of Pluto

42 Misconception Pluto s discovery relied on mathematical predictions based on perturbations in Neptune s orbit.

43 Misconception Pluto s discovery relied on mathematical predictions based on perturbations in Neptune s orbit. Pluto s discovery relied solely on the incredible observing skill and dedication of Clyde Tombaugh. Neptune s orbit shows none of the claimed perturbations.
