Overview
ℹ️
NGC 2239 is a poorly populated, moderately dense object of high C3 quality. Its parallax locates it at a relatively close* distance, near the mid-plane, affected by high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 6 years.

(*): The parallax distance estimate (~1.49 kpc) differs significantly from the median photometric distance (~3.51 kpc).

Note: This object shares a moderate percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
