Overview

ℹ️

HSC 1093 is a sparse, very dense object of very high C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a metal-poor, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~7.43 kpc) differs significantly from the median photometric distance (~4.54 kpc).

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