If you need only approximate answers then you can assume that the planets are all in the same plane, and use Kepler's laws (very simple geometry) to calculate the positions based on a known set of initial positions at a given date and time. You could modify your inital conditions occasionally to maintain reasonable accuracy. Please contact me privately if you wish to pursue the idea, this is way Off Topic for this list. 73, Ged.
Re: Astronomical Information
Around 1996, I ported./worked on an AIPS( Astronomical Image Processing Sysetm) software to Linux. See http://www.aoc.nrao.edu/aips parhaps they have some Perl API by now.. simran wrote: > Hi All, > > I have (for weeks) been trying to find a Perl Module (preferablly one > that works under mod_perl) that does various astronomical calculations - > in particular i want to be able to work out the distance of a planet (in > our solar system) on a given date. > > Maybe i have been searching for the wrong keywords or been looking in > the wrong places but i have tried AltaVista, Google, Some NewsGroups > etc. There are references to C libraries that can do it (but aren't > free) but no references to perl modules that can do the above. > > If anyone has any information on any such modules, i would apprecaite > very much if you could share the modules with me (and possibly others by > putting them on CPAN). > > simran. -- - Medi Montaseri [EMAIL PROTECTED] Unix Distributed Systems EngineerHTTP://www.CyberShell.com CyberShell Engineering -
Re: Astronomical Information
'tis was the first place i looked (but forgot to mention in my email) :-) but the modules there are rather limited in what they do. Anton, perhaps we should write the module and put it there, i loaned the book "Astronomical Algorithms" from the library, but the formulas in it are not trivial and i would really need an "astronomer" to give the formulas to me... coding them them and putting them on CPAN would then be no problem.

Astronomical Information
Hi All, I have (for weeks) been trying to find a Perl Module (preferablly one that works under mod_perl) that does various astronomical calculations - in particular i want to be able to work out the distance of a planet (in our solar system) on a given date. Maybe i have been searching for the wrong keywords or been looking in the wrong places but i have tried AltaVista, Google, Some NewsGroups etc. There are references to C libraries that can do it (but aren't free) but no references to perl modules that can do the above. If anyone has any information on any such modules, i would apprecaite very much if you could share the modules with me (and possibly others by putting them on CPAN). simran.
