I added the proper textures to all of the planets to make them look more realistic.

I changed the orbits of several of the planets to rotate around in a strange way.

I had the camera move around the sun and rotate to follow the planets.

I added a skybox to be a background for the animation.

I made mars to be Elon Musk's idea of the future. I also made it orbit much faster around the sun.

I had the sun eat Venus.
