I'll elaborate on what I'm working on to show you what the problem is. I'm building a software display that shows the actual position of the moon and Earth in relation to the sun from a top down 2d perspective of the ecliptic plane. So I've found the position of the moon in relation to the Earth...
My bad, I think I need to be more specific. I'm referring to an ecliptic coordinate system found here https://en.wikipedia.org/wiki/Ecliptic_coordinate_system . From this page I think 0 degrees would be the vernal exquinox. However, now I need to know the position of the Earth in this system as...
I'm attempting to use an algorithm translated from Jean Meeus: Astronomical Algorithms. The algorithm in question finds a geocentric position of the moon given a certain day. I have been able to find the geocentric longitude of the moon, but I don't know what this longitude is in reference to...
