Overview

ℹ️

CWWDL 3813 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a moderate distance, below the mid-plane. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It was recently reported in the literature.

Note: This object shares a large percentage of members with 3 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.

Near-solar metallicity Very young
