Overview

ℹ️

HSC 2512 is a sparse, very dense object of intermediate C3 quality. Its parallax locates it at a large distance, near the mid-plane, affected by high extinction. It is catalogued as a very massive, near-solar metallicity, very old cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.

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