Epsilon Eridani (10.5 ly)
Procyon (11.4 ly)
61 Cygni A (11.4 ly)
61 Cygni B (11.4 ly)
Epsilon Indi (11.8 ly)
Tau Ceti (11.9 ly)**
Groombridge 1618 (15.9 ly)

That's 9 possibles on a very optimistic scale; reality is probably limited to about half those.


* I don't consider M-class red dwarfs suitable due to the high probabilities of tide-locking and flares frying most planets that would be in the life zone.

K-class = orange dwarf
G-class = yellow dwarf
F-class = yellow-white

** It is possible that Tau Ceti has two planets in its habitable zone, but I only counted it once above.

Sorry for the late reply,n but if it helps I've got a system built with Space with two habitable around a F9 and three each around a G0 and a G4
