Overview

ℹ️

HSC 2365 is a poorly populated, dense object of intermediate C3 quality. Its parallax locates it at a very large^* distance, well below the mid-plane, affected by low extinction. It is catalogued as a very old cluster (see Parameters). It was recently reported in the literature.

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

(*): The parallax distance estimate (~13.57 kpc) differs significantly from the median photometric distance (~5.31 kpc).

Very distant Low extinction Very old
