Was fun zooming out and comparing stars to the cubic area. If it's a sphere, we're at about 250 cubic light years per star at both 12.5 lt yr out, and at 20. It heads to around 900 ly^3 per star when you look at everything within 5000 lt yrs.
Makes sense, given that the Milky Way--while 150-200 kly wide--is only about 2000 light years thick.
Of course, we could rapidly zoom much, much farther out, like in this intergalactic redshift survey:

Space is incomprehensibly big.
