Overview

ℹ️

NGC 7429 is a rich, loose object of very high C3 quality. Its parallax locates it at a very close^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a low-mass, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~0.42 kpc) differs significantly from the median photometric distance (~1.25 kpc).

Note: This object shares a significant percentage of members with 3 later reported entries. See table with shared members information.
