Overview
ℹī¸
ESO 429 02 is a poorly populated, moderately dense object of high C3 quality. Its parallax locates it at a moderate* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~3.21 kpc) differs significantly from the median photometric distance (~2.06 kpc).

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