Overview
ℹī¸
Loden 46 is a poorly populated, very dense object of intermediate C3 quality. Its parallax locates it at a relatively 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 age and metallicity parameters (see Parameters). It is very well-studied in the literature.
Relatively close Low extinction Near-solar metallicity Intermediate age
