AI Drawing Prompt Reference

Draw a dynamic solar system with elliptical orbits. Start with two intersecting axes to create a sun at the center, then draw a unit circle around it. Create multiple elliptical orbits by rotating and drawing rays, determining each planet's path through intersection points. Represent each planet as a small circle on its respective orbit. Adjust the angles and sizes of the orbits to simulate the planets moving around the sun, showcasing celestial motion and elliptical paths.
