This is the animation produced from following the tutorial
List of Changes:
I changed the textures of the planets, moons, and the sun to be more realistic. All of the moons are photo accurate except for the moons of Uranus, Neptune, and Pluto because there is no good image of them so I used the same basic moon texture for them.
2. Next I added a starry background to give it more of a space feeling
3. Lastly I changed the orbits of the planets.
Earth and Mars follow the same orbital path which never reaches the far side of the sun.
Uranus orbits about 3x faster than the other planets
Some of the planets have different starting positions
