Overview

ℹ️

OC 0412 is a poorly populated, very loose object of intermediate C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~8.27 kpc) differs significantly from the median photometric distance (~5.71 kpc).
