Overview
ℹī¸
NGC 2360 is a very rich, very dense object of very 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 massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the absorption, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

Note: This object shares a very small percentage of members with 2 later reported entries. See table with shared members information.

Malhotra et al. (2026)
Lowest/Highest stellar mass in the catalogue with a mass-ratio estimate: 0.49/1.81 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).

Ahumada & Lapasset (2007)
Stars 51 and 100 are cited as blue stragglers in (1968ApJ...152...83E) and (1994AJ....108.1828M). The last reference also considers stars 1, 69, and 82 (WEBDA numbers) as stragglers. Adopted cluster centre: star 46 (1968ApJ...152...83E).
