I'm writing a program that models objects in our solar system in 3D with lots of functionality. (Senor Project in Computer Engineering), since alot of time an effort has gone into this software so far, I'd like to implement the most accurate details to configure several objects. By objects, I mean planets, satellites, and dwarf planets. Comets would by interesting too. On wikipedia, I found it hard to copy the data each page by page, not to mention some things are not filled out, (inclination is set to ecliptic / sun's equator). On nasa, i havent found any good tables, yet (confusing to navigate). Since this is the astronomy forums, perhaps anyone has an idea of a good source? Again, I am not an astronomer, but I love space and guided my project to this (I do know some astronomy to calculate the planetary motion). Thanks in advance! When I finish my program, perhaps I can share it with all. It wont be as near as good as Universe Sandbox or anything, but it is in a different way, a simulation.
