Overview
ℹī¸
COIN-Gaia 24 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is well-studied in the literature.

Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.

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