Visible Planets appears to work fine, since my last post a turned it back on and it works. The error occurs once HD Planets is enabled, so either HD or your mod have to be enabled without the other. I saw lines of code that refer to if this mod = true so-on and so-forth in the Visible Planets I believe, and I'm using both currently just fine. If you're working on a fix for HD Planets it could solve the issue entirely and could possibly be replicated with any new planet that had issues with HD's 4072 sizing.
This is what the HD data.lua has in my folder, as I was attempting to fix it myself without success. I added the exception to insert this planet if the mod is present, and then attempted to manually add a 4072 .png to the HD folder (unzipped) but couldn't find any free upscaler that let me go above 4000px so I don't know if simply making the file 4072 would fix it half-assedly between the mods or if it's a separate issue entirely between them.

for _, name in pairs(planets) do
local prototype = data.raw["space-location"][name] or data.raw["planet"][name]
if not prototype then
log("WARNING: missing space location: "..name)
else
prototype.starmap_icon = "hd_planets/graphics/"..name..".png"
prototype.starmap_icon_size = 4072
end
end

Trying to help with as much leg-work as I can, I'm fairly extremely inexperienced other than fudging around until things work-ish.
