    equasions (help!!)

    I am currentally working on a dossier project for my Java class and wanted to know if anyone knows if there are certain equasions for the following:

    1) Phase of the moon given the date
    2) Cordinates of planets given date, time, and longitude/latitude

    The American Ephemeris and Nautical Almanac can be purchased from:

    WASHINGTON, D.C. 20402

    You must specify the year you want.

    Expert Software has a CD-ROM called RedShift 2.

    You won't find any equations from either of these, but they will tell you the positions of the sun, moon, planets and stars.
    I hope this helps. -Mike

    A little late, but there are some books you might want to check out to assist with this sort of stuff:

    Practical Astronomy with your Calculator, Peter Duffett-Smith (Cambridge University Press).

    Practical Astronomy with your Personal Computer, Peter Duffett-Smith (Cambridge University Press).

    Astronomical Algorithms, Jean Meeus (Willmann-Bell).

    Spherical Astronomy, Robin M. Green (Cambridge University Press).
