1. I changed the surface of the texture of the planets so that they are more realistic.
2. I changed the shape and orbit of Saturn and its ring. The planet is now a flat disc that rotates on its Z-axis, and its ring is perpendicular to the planet's center and rotates on its X-axis.
3. I altered the orbital pattern of every other planet so that half orbit on the X-axis and half orbit on the Y-axis.
