Overview

ℹ️

NGC 2234 is a sparse, loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.48 kpc) differs significantly from the median photometric distance (~3.92 kpc).

Distant Moderate extinction Near-solar metallicity Intermediate age
