I'm wondering if there's any good computer software for tracking the orbits of planets over time. I like to see the orbit's trails against the sky background.

I'd prefer something that's free and of a good quality.

I've already tried Google Earth, but it doesn't seem to be able to do this.

There are either too many possible answers, or good answers would be too long for this format. Please add details to narrow the answer set or to isolate an issue that can be answered in a few paragraphs.If this question can be reworded to fit the rules in the help center, please edit the question.

Are you looking to create new data (make your own observations, etc) or browse historical/current data from other people? – Undo Oct 10 '13 at 20:56
What do you mean by tracking? Do you want to plot the orbits of planets? Do you want to track them in real life, using your PC and s motorized telescope? Please clarify. – Arne Oct 10 '13 at 21:08
@Undo Both, @ Ame I want to plot them, not real-time tracking. – Timtech Oct 10 '13 at 21:33
I'm closing this because it's an overly broad shopping question. Shopping questions are fine if they call for expertise from the community. This could be a really interesting question if you edit it to explain what you are hoping to do with the software. – Jon Ericson Oct 10 '13 at 21:39
Stellarium is free, open source and it allows you to display planet orbits. Here's a wiki page describing the required settings. – toniedzwiedz Oct 12 '13 at 10:06
