Overview
Theia 2651 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a moderate* distance, near the mid-plane, affected by high extinction. It is catalogued as a metal-poor, intermediate-age cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~3.45 kpc) differs significantly from the median photometric distance (~2.52 kpc).
Note: This object shares a small percentage of members with a later reported entry. See table with shared members information.
â ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
