Oh yea if it's a result of an error in the algorithm that's fine, yea. I was just surprised.The technique (Stellar Forge) Frontier uses to generate the star systems sometimes (read rare) creates weird systems. When such a thing happens and gets detected it'll get patched in a future update. In older versions it was there was a planet that had an orbit inside the rings of another planet.
In a game with 400 billion systems a few are bound to have errors.
