Overview

ℹ️

Dutra Bica 45 is a sparse, very loose object of low C3 quality. Its parallax locates it at a very large^* distance, well above the mid-plane, affected by very high extinction. It is catalogued as a low-mass, old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~53.48 kpc) differs significantly from the median photometric distance (~1.19 kpc).

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Relatively close Very high extinction Low mass Old
