Overview

ℹ️

Collinder 223 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~3.72 kpc) differs significantly from the median photometric distance (~1.69 kpc).

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

Relatively close Low extinction Near-solar metallicity Intermediate age Contains BSS

Ahumada & Lapasset (2007)
Stars 35 and 80 are cited as blue stragglers in (1991PASP..103..998C). Star 2, which also appears as a blue straggler, is at 3.5 cluster radii from the centre, which has been set on star 84 (ref. 80). Star 35=HD 305295, star 80=HD 305218.
