i would agree to what @plane918273645 said

just land on the sun to be in a geosynchronous orbit

I think you may be more looking for the geostationary orbit information. It's some nice math, but I found the KSP wiki has a good article about it. It's labled as "Geosynchronous Orbit (Math)" but explains more how to find the geostationary, which is similar but I think more what you're looking for. That article does a much better job explaining than I can.

@plane918273645 LOL 🤣 even if it did, it wouldn't matter anyway since there's no reason to orbit over the same spot on it's surface anyway(there's no sunspots to count unlike irl)

Juno is the sun. It doesn’t rotate.
