Overview

ℹ️

HSC 2043 is a moderately populated, moderately dense object of high 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 (see Parameters). It was recently reported in the literature.

⚠️ Warning: This is possibly a duplicate object, which shares a significant percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~5.58 kpc) differs significantly from the median photometric distance (~4.08 kpc).
