Overview

ℹ️

Antalova 2 is a moderately populated, loose object of intermediate 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, very young cluster, but with a large variance across recent sources for the absorption and metallicity parameters (see Parameters). It is moderately studied in the literature.

Relatively close Moderate extinction Near-solar metallicity Very young
