The Stars, My Brothers He wasn't used to maneuvering without gravity; he'd been taught it in Cadets, of course, but that was years ago and parsecs away. The Measure of a Man Rustum, e Eridani II, was six parsecs away, forty-one years of travel, and barely habitable: but the only possible world yet discovered.

Evil Out of Onzar He operates in all the systems for a hundred parsecs around, and he never sinks a dry hole. Subspace Survivors It didn't reach them, and it went so far that the distance is absolutely meaningless, even expressed in parsecs. Skylark Three We missed our objective, probably by many millions of parsecs, and it is quite possible that we four will never be able to find our way back. The Galaxy Primes "What do you expect, with General Headquarters thirty parsecs from the fighting?"

Plague Ship Half their fleet tied up hundreds of parsecs away, the rest barely more than what we have here.
