Quote from Wiki https://en.wikipedia.org/wiki/Retrograde_and_prograde_motion
In the Solar System, all of the planets and most of the other objects that orbit the Sun, with the exception of many comets, do so in the "prograde" direction, i.e. the same sense as the rotation of the Sun. Also the rotations of most planets are prograde, with the exceptions of Venus and Uranus, which have retrograde rotations.

The following simulation let you play with it.

The green dot is draggable. You can use slider bar to change the observer star (green dot).
All the velocity(arrow) are draggable,too!

The right side view shows the relative motion (related to the observer star).

  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
