Overview

ℹ️

CWNU 3117 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~4.11 kpc) differs significantly from the median photometric distance (~3.02 kpc).

Note: This is very likely a unique object, which shares a small percentage of members with at least one previously reported entry. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.88) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
