How about - the one known star less than a light year away is not binary
so it is not believed possible for it to nova.  It is also not massive enough
to become a supernova.

(Actually, I'm not sure I got that 100% right - can a massive non-binary
star nova?  Also, just what *is* the difference between a type A and a
type B supernova?).
