    Hi,
    I have plans to write an open-source astrology library in Haskell (because frankly, the leading software sucks, are opaque, and does not do what I want it to do). I had come up to the same question. Here’s what I found so far:
    – Jet Propulsion Lab Horizon. It tracks and predicts many celestial bodies and accounts for perturbations, etc. However, you can only access it by HTTP requests or through Telnet.
    – libnova. This is a C library that is open-source. It uses VSOP87 which is the leading theory for calculating planetary motion.
    – pyephem – Python library. I would probably use this one if I weren’t planning on writing this in Haskell.
    You might want to check out this page for some of the differences:

    Looking at this, it is a relief not to have to write this stuff. These models can get very complicated, and the various astrology systems are themselves involved as well.
    Let me know if you want to chat sometime.
