Overview

ℹ️

Bica 3 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by very high extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~2.49 kpc) differs significantly from the median photometric distance (~1.64 kpc).

Relatively close Very high extinction Near-solar metallicity Very young
