Overview

ℹ️

HSC 2110 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a large^* distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, old cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~8.51 kpc) differs significantly from the median photometric distance (~6.12 kpc).

Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
