Overview

ℹ️

CWWL 2987 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate distance, above the mid-plane. It is catalogued as a metal-rich, intermediate-age cluster (see Parameters). It was recently reported in the literature.

Note: This object shares a significant percentage of members with 2 later reported entries. 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.
