Heliocentric Solar System

Dive into the revolutionary findings of Galileo Galilei and Nicholas Copernicus, who challenged the geocentric model by unveiling the heliocentric system. Explore how these pioneering scientists used telescopes to observe celestial bodies, leading to groundbreaking revelations about the sun, planets, and stars. Discover the intriguing concept of retrograde motion and how the heliocentric model offers a new perspective on the movements within our solar system. Unravel the mysteries of the cosmos through the eyes of these iconic astronomers.

  1. Heliocentric Solar System

  2. BELLWORK: What did the solar system do when it wanted to have a party? plan it!

  3. Galileo Galilei(1564 – 1642) 1610 “SideriusNuncius” (The Starry Messenger) Used a handmade telescope to view the sky. "Eppur Si Muove“"(And, yet it moves!")

  4. The Moon has mountains, valleys, craters, just like Earth!So… we (Earth) is not so special. The objects in the solar system are similar. Galileo Galilei (1564 – 1642)

  5. Galileo Galilei (1564 – 1642) Sunspots on the Sun moved across the face of the Sun, so….. What is the sun doing? The sun must be rotating, spinning! So….. Does the Earth also spin, rotate? SUNSPOTS

  6. Jupiter Has Moons! Galileo’s 4 Moons – Io, Europa, Calisto, & Ganymede Big Jupiter has several moons orbiting it! So….. Could the Sun have planets orbiting it too?

  7. More evidence… With his telescope, Galileo observed that Venus has phases, just like our moon! Over the months of the year, Venus can be observed changing in size and going through phases

  9. Nicholas Copernicus(1500 AD) (a thousand years after Ptolemy In Europe) The HELIOCENTRIC Model “De RevolutionibusOrbiumCoelestium”

  10. A New and Improved Model Using Galileo's observations with the telescope, Copernicustried a different model, placing the SUN in the CENTER with the planets orbiting around it. HELIOCENTRIC Let’s see if it explains retrograde motion.

  11. Copernicus Explains Retrograde Motion Planet's apparent path around sky. 6 6 5 5 4 3 Sun 3 2 2 4 Earth 1 Fixed Stars 1 Mars orbit Fast Earth overtakes slower outer planets so they appears to slow down, move in reverse, and then move forward again with respect to the fixed stars.

  12. “On the Revolution of the Heavenly Spheres” Retrograde Motion was much simpler to explain If….. Earth is NOT the center of “everything.” The SUN is at the center of the solar system Any observed movement of the Sun is due to Earth’s revolution (orbit) and rotation about the Sun. The apparent motion of the stars is a result of the Earth’s rotation also, the Stars are much farther away than the Sun
