Hey i thought this might be a question for you guys.
The white circles around visited systems on the Galactic Map. Whats the cap before old ones disappear? Or is there a different cause like distance/time away from the region that causes them to vanish?
Been working on the Haven 3d map project and it seems like it might be handy info to have for folk plotting entire regions.
No idea. I have a region I will go check on. Been exploring it for several years now. As far as I can tell, they are all still highlighted and my path to them still shows.
I never quite figured that out when I had been doing full region data research, but I do know, in the galaxy map, you can at best visually see close to 200 ‘visited system’ icons, or possibly ‘icons’ in general. It will include their paths and labels as well of course. There can possibly be more marked systems, but there is a render distance for these icons (and paths) involved too, so some will start to fade. Here is an image from this research ( created May 2022), where I marked 182 ‘visited system icons’ (light blue) for as best I could see.
These icons used to persist as well when switching galaxy (see images below). So I assume the icons are just being referenced by an indexed list, unrelated to the actual discoveries made.

This same location as above after having changed galaxy (Hilbert)
… changed to Calypso
… Hesperius
Things may have changed over time, as my research into this has been a few years back by now. I do know the save data can store 512 VisitedSystems max. So there is that limit at least, which is most likely ‘fixed’ and does loop around, similar to the teleport locations at a Space Station. I bet the visibility of the icons in the galaxy map can be messed with. Possibly a maximum defined, but most certainly a render distance value somewhere in the files.
Legendary breakdown and fantastic research as always 
The two caetographers who I gave the heads up to about the marker cap actually hit it and then counted them. Seems its gone up to 250 now. (Both playing on console)
Also their plotted region reminded me of Fl0w 
Thanks again so much @DevilinPixy 
@toddumptious I have created a new topic for this discussion here
