Overview
ℹī¸
NGC 5460 is a rich, very dense object of very high C3 quality. Its parallax locates it at a close distance, above 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 metallicity parameter (see Parameters). It is very well-studied in the literature.

Malhotra et al. (2026)
Lowest/Highest stellar mass in the catalogue with a mass-ratio estimate: 0.45/3.25 Msun

Almeida et al. (2025)
Mass determination: good 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 9.7, 0 WD candidates found, and 0 WD candidates found in the wide search.

Hu et al. (2021)
Ellipticities (core, all): e_core=0.0984, e_all=0.1433.

Rain et al. (2021)
This cluster was include in (Dias et al., 2002A&A...389..871D, Cat. B/ocl) however, parameters log(t)=8.110, Av=0.328, [Fe/H]=0.030 were taken from Bossini et al. (2019A&A...623A.108B, Cat. J/A+A/623/A108).

Ahumada & Lapasset (2007)
Star 66, which appears as a straggler, is a non-member (1993A&AS...99....1C).
