Overview
ℹī¸
ESO 332 08 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a relatively close* distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

⚠ī¸ Warning: This is likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~1.73 kpc) differs significantly from the median photometric distance (~1.20 kpc).
