Overview
ℹī¸
NGC 2302 is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, near 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.

Palma et al. (2025)
Classified as optical pair (not dynamically associated) P102, along with CWNU_1503.

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

Cavallo et al. (2024)
Gold sample.

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

Hunt & Reffert (2023)
Classified as open cluster. CMD class: 1.00 (50th percentile).

Richer et al. (2021)
The expected number of WDs is 8.7, 0 WD candidates found, and 0 WD candidates found in the wide search.

Hu et al. (2021)
Ellipticities (core, all): e_core=0.3037, e_all=0.2531.

Rain et al. (2021)
This cluster was include in (Dias et al., 2002A&A...389..871D, Cat. B/ocl) however, parameters log(t)=7.873, Av=0.636, [Fe/H]=0.00 were taken from Bossini et al. (2019A&A...623A.108B, Cat. J/A+A/623/A108).
