What were the main objections Copernicus had to the Ptolemaic system?


Two Week Assignment: We will spend the next few weeks looking at individual planets. Please post a planet report to the Moodle site by the start of our chat session on Kepler (the next unit). Be ready to answer questions about "your" planet from your fellow students!

Claim your planet in our session on Copernicus, then and write a short report on it. Describe its basic characteristics, identifying:

  • Is it a Jovian or terrestrial planet?
  • Describe its relative size, distance from the sun, length of solar year, length of solar day (rotation on its axis), tilt of axis with respect to the plane of its revolution.
  • What is its atmosphere made of (if any)? How does the atmosphere affect the planet's surface temperature?
  • Does the planet have water or evidence of water in the past? Why would this be of interest to earth explorers?
  • Is the planet "active" -- does it have volcanoes or planetary quakes?
  • What are its interesting surface features?
  • What is its core structure? How do we determine this structure? How does it influence the planet's affects on nearby space?
  • Does it have moons?
  • What are the past and current efforts to explore this planet?
  • Add any other information that you find about the planet that you think is interesting


Instead of uploading a worksheet, you'll enter your answers into a Moodle Exercise. It looks like a quiz, but it is different in several ways:
