Hello CMDRs o7,
My theory from canonn discord,
(although if someone else said the same before me, then of course it's their theory but not seen it yet here ^^)
So previous ruins site was at the following location. The vertex of a roughly equilateral triangle made from 2 ejecta lines and a ridge/canyon.
This is going off the fact that guardians like geometric shapes etc.

So there is one instance of this occurring in the following system. i.e. it's the only planet in that system which has this feature.

It's the same moon as the one with the space trees, which occupy the major crater in this triangle.
Top vertex Coords are 24,54 bottom right coords I think are 8,60.
Since this moon is quite small it's easy to make a pass across the length of the ridge at 300m/s within a few minutes
But I could use more eyes. If you are nearby please message me on the discord. Could be fun could be nothing.
Happy hunting CMDRs!
