I've been following the answer given by Mike G here: How to calculate the orientation of planets at current epoch to get planets to have the correct orientation in my program, but all the angles are in the Invariable plane, how is that converted to the J2000 ecliptic plane? I've been stuck at this for hours and it makes my head hurt, any help would very much be appreciated!

1$\begingroup$ Can you edit your post to give us more details? For instance, are you developing an app (as in the linked question)? Are you using the approach set out in Mike G's answer? Was the OP's comment to that answer useful? The more you can tell us about what you're trying to do, the more likely someone will be able to post the solution you're after. $\endgroup$– Chappo Hasn't ForgottenCommented May 10, 2021 at 5:35
