Galactic Planetary Nebulae Catalog

Metadata Updated: September 19, 2025

This is the 1992 Version of the Strasbourg-ESO Catalog of Galactic Planetary Nebulae (Acker et al.1992). It includes 1143 true and probable planetary nebulae (from Table 1 of the publication) and 347 objects whose status was still unclear and were thus classified among the "possible" planetary nebulae (from Table 2 of the publication); it does not include 330 objects once considered as possible planetary nebulae but which the authors have since rejected (listed in Table 3 of the publication). The designation system for the planetary nebulae listed in this catalog follows the recommendations of IAU Commission 5 (Astronomical Nomenclature) with the structure: "PN Glll.l+bb.b", where PN means "Planetary Nebula", G stands for "Galactic Coordinates", and lll.l+bb.b are the galactic longitude and latitude respectively, truncated to one decimal place. Copies of the complete catalog, including the Finding Charts (Part I) can be ordered from the ESO Information Service, Karl-Schwarzschildstr. 2, D-85748 Garching bei Muenchen, Germany. This database was created by the HEASARC in May 2001 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/V/84">CDS Catalog V/84</a>, tables main.dat, diam.dat, dist.dat, dista.dat, hbeta.dat, iras.dat, nir.dat, radio.dat, vel.dat, cstar.dat, and pospn.dat. This is a service provided by NASA HEASARC .
