Overview

ℹ️

NGC 2239 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a relatively close^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly 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 is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry. See table with shared members information.
