The facts

Abell PN 14 is a planetary nebula in Orion. SIMBAD gives its distance as 3.380 kpc (−0.676 kpc / +0.676 kpc) — ≈ 11,020 ly from 2 measurements. The light reaching us from it now left it about 11,020 years ago, around the end of the last ice age. SIMBAD measures it at 0.5′ × 0.5′ on the sky — 2% of the full Moon's width. At that distance, that angle means it is roughly 2 light-years across. Framing uses its catalogue size instead: 0.6′.
