im consttructing my own solar system sim called "astrometrics". I need data for the planets and moon's displacements relative to time... i need to know at what part of their orbit they will be at any point in time... where can i get data like that? Also i need to know the displacement of their apogee and their peragee etc.
Im not sure what frame of reference is standard, but ill take anything. im assuming celestial sphere is the standard or the ecliptic plane.
ive got all the other data like radius and rotation and orbital periods. Just need to know where a planet is gonna be and when it will be there.
PLEASE email me if u can help
