"Historical Models of the Solar System"

Storyboard Text

  • If Earth was to go around the sun, the location of stars would change
  • Aristotle (384-322 BCE) He was a Greek philosopher, His solar system model proposed that the other planets and stars orbited around the earth, his reasoning being that stars would change positions if the earth was the one orbiting the sun. Even though his models were far from accurate he contributed to the idea that the planets and stars orbit around a body in the solar system
  • Acording to my observations and model, the the sun is the center of everything.
  • no it isn't, go look at aristotles studies.
  • Aristarchus (about 310-230 BCE) He was a Greek astronomer and mathematician. He proposed a heliocentric model of the solar system, but it wasn't very accepted.He tried to measure the distance to the moon and the sun, the distances were too small but nevertheless it contributed to prove that the use of observation and geometry is important to solve a scientific problem.
  • Celestial bodies must travel at a constant speed in a flawless circle!
  • Ptolemy (about 100-170 CE) He was an astronomer, geographer, and mathematician who lived in Egypt. He wrote a book about observations of planets which goes back to 800 years, he contributed by developing a geocentric model that was used for the next 14 centuries, and also by using a wheels-on-wheels system that was used to further develop the solar system model.
