Overview

ℹ️

Dutra Bica 58 is a sparse, very loose object of 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 low-mass, very young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.31 kpc) differs significantly from the median photometric distance (~1.18 kpc).

Note: This object shares a small percentage of members with a later reported entry. See table with shared members information.

⚠️ 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 Very young
