Overview
ℹī¸
ESO 430 09 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a moderate* distance, above the mid-plane, affected by low extinction. It is catalogued as a metal-rich, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~3.70 kpc) differs significantly from the median photometric distance (~2.75 kpc).

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