As we talk about upcoming oppositions for Mars and the angular sizes of Jupiter and Saturn and Venus, I find that I would really like to be able to get a top-down view of the solar system that I can move forward and back in time. I know that planetarium software like SkySafari or Stellarium exists, but I don't know of one with the top-down outside of the solar system view. I'm an applied math guy so I could certainly solve some differential equations and make my own visualization, but I imagine this problem has already been solved.
What software is out there that can show me the orbital positions of the planets in the solar system with easy controls to move the date?
Thanks in advance for your suggestions.
