Overview

ℹ️

HSC 2794 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by very high extinction. It is catalogued as a massive, intermediate-age cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~4.92 kpc) differs significantly from the median photometric distance (~3.78 kpc).

Note: This object shares a moderate percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
