Overview
ℹ️
NGC 2669 is a rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

Almeida et al. (2025)
Mass determination: good fit. Isochrone match: good fit. Gold sample.

Cavallo et al. (2024)
Gold sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD class: 1.00 (50th percentile).

Richer et al. (2021)
The expected number of WDs is 12.3, 0 WD candidates found, and 0 WD candidates found in the wide search.

Ahumada & Lapasset (2007)
Star 24 = HD 75067 (sp. B8/9IV/V(n)) (1975MSS...C01....0H). Adopted cluster centre: star 8 (1973A&AS....9...97V). Star 2 appears as a straggler but is a non-member according to (1979, Sydney Obs.Pap., No.86).
