Did somebody say "ELW" and "rare"?
Funny you should ask about how rare it is, because later today I'll add a "rarity score" to the ELW list. Once that's done and your find is on the list, you'll be able to find out how rare it is compared to the planets on the list. I can already tell you this is extremely rare though, because of the following factors:
- ELW moons orbiting a dwarf star are extremely rare (8 out of 7208 so far, and most of those eight are around class M dwarfs)
- ELW-s in systems where the sole primary star is a black hole are extremely rare (6 out of 7208)
- ELW-s in mass code F systems are extremely rare as well (6 out of 7208), although this is mostly tied to star types
Oh, and it's also tidally locked, which is moderately uncommon too. Don't have precise numbers on it yet.
So, congratulations! You have an extremely rare find there. Right on, Commander! And congrats on reaching Elite to boot.
Oh, and you needn't bother with submitting the ELW to the list, I've got the screenies and all the info I needed from EDSM. Thanks for submitting it there too!
As a curiosity, it is possible for an ELW to exist around a solitary L dwarf system (so nothing but an L dwarf there), but only one such system has been found so far. That's
Droju IG-M a103-0, first discovered by CMDR Veersarge.
