My next change for the planets themselves was on their orbits. I staggered the orbits so they were no longer traveling in a line around the Sun. I also adjusted the speed of orbit for each of the planets to reflect their real revolution time. I calculated the degrees of orbit each planet would go over the course of two Earth-years so they revolve around the Sun with their real relative orbital speed. The images below show the planet alignments on the initial frame for the tutorial and modified animations.
