Overview

ℹ️

ESO 429 05 is a rich, moderately dense object of high C3 quality. Its parallax locates it at a large^* distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~9.90 kpc) differs significantly from the median photometric distance (~5.22 kpc).

Note: This object contains blue stragglers according to at least one source.

Very distant Moderate extinction Near-solar metallicity Old Contains BSS
