Overview
ℹī¸
COIN-Gaia 10 is a moderately populated, very dense object of intermediate C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (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.
