Overview
ℹī¸
NGC 1896 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a close* distance, near the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, old cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~0.85 kpc) differs significantly from the median photometric distance (~1.66 kpc).

Relatively close Low extinction Near-solar metallicity Old
