Good F***ing Luck with These, because at best only a handful have been found (<0.025%):
I was recently about to fly a helium-rich boxle, there was also an
L-type starsystem and then I was extremely surprised about this message from one of my tools:
New personal record: Smallest distance from the entry point of an earth-like planet: 11.2830 LS
And then it wasn't just one!
I will submit the system map later when the servers are up and running again.
For now, here is the star and the first three planets from my tool.
Update, as I just noted on EDAstro, this would be the very first finding of more than one Earth-like around an L-type star
