Overview

ℹ️

HSC 759 is a rich, very loose object of very high C3 quality. Its parallax locates it at a very close distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It was recently reported in the literature.

Note: This is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry. See table with shared members information.
