Nocilaus Copernicus1543 A.D. Published Heliocentric Theory

Helio = Sun, Centric = MiddleHeliocentric modelTheory was not popular especially with

religious organizations

Tycho BraheFavored the geocentric modelBrahe Geocentric ModelSun and moon orbit EarthAll other planets orbit the Sun

Johannes KeplerWorked as Brahe’s assistantFormulated 3 laws of Planetary motion

1st = Orbits are an ellipse2nd = Planets move faster closer to sun3rd p²=a³

Favored Heliocentric ModelSun not exact center of orbits

Galileo GalileiUsed telescope to observe celestial

bodiesDiscovered Galilean Moons of

Jupiter, sunspots, physical features on moon

Favored Heliocentric modelUsed phases of Venus to support

model

planets to orbit around the sunThat force is……..Gravity
