Overview

ℹ️

HSC 1480 is a poorly populated, very loose object of intermediate C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age 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 (~5.83 kpc) differs significantly from the median photometric distance (~4.40 kpc).

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