Overview

ℹ️

CWNU 3895 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large^* distance, well above the mid-plane, affected by moderate extinction. It is catalogued as an old cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~7.78 kpc) differs significantly from the median photometric distance (~5.50 kpc).

Note: This object shares a very small percentage of members with at least one entry reported in the same catalogue. 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.
