Science - Astronomy & Space
English term or phrase: reference frame
2) It is absolutely true that in an Earth-centered reference frame the sun rotates about the Earth, but, the other planets do not have orbits around the Earth. From a sun-centered reference frame all planets revolve around the sun, so that's another reason the sun-centered reference frame is more convenient. If you track a planet's motion across the night sky over the course of months you will see it retrogress, or go backwards from its normal direction for a few days or so at a time. When astronomers (like Galileo? I wish I remembered) first noticed this they knew it was evidence that the planets do not revolve around the Earth. You could look for planet retrogression as an assignment for your class by asking your students to track some planets across the night sky with the rest of the stars as a reference frame. I did that once when I was a student in Minnesota. It's amazing what you can see with just the naked eye and a pencil and paper!
