Overview
ℹī¸
NGC 2358 is a rich, moderately dense object of high C3 quality. Its parallax locates it at a 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 absorption and metallicity parameters (see Parameters). It is well-studied in the literature.

Liu et al. (2025)
Classified as tidal capture (resonant trapping binary) 283 along with Theia_366, and of multiple system 60 along with HSC_1843 and Theia_366.

Palma et al. (2025)
Part of multiple system G215, along with HSC_1843 and Theia_366.

Almeida et al. (2025)
