The closest PN are
A35, 408 light yrs
NGC7293 Helix, 655 light yrs
PHL932, 1014 light yrs

The attached file gives the distances to 144 PN using the data from Gaia.
I looked at images of all the PN and selected the larger ones.

The data given is Name, Dist in lt yrs, G mag of central star, RA hrs, dec deg, PNG
It is sorted by RA.

Hi Glen,

Thanks mate -- determining accurate distances to PNe has been a bug-bear afflicting astrophysicists for decades. Glad to see it is now being resolved somewhat.

Best,

L.
