Great project! I learned a lot while working on it. One of the challenges I encountered was ensuring that the active state matched the color of each planet. It took some time, but I eventually figured it out.

If I have any questions, my main focus would be on how to make the planets vary in size. For example, I would like to make Jupiter the largest planet and ensure that Mercury is smaller than Earth. I'm excited to explore different strategies for achieving this size variation among the planets.
