Overview
HSC 2287 is a poorly populated, very dense object of intermediate C3 quality. Its parallax locates it at a large* distance, well above 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 (~8.37 kpc) differs significantly from the median photometric distance (~6.31 kpc).
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
