Overview
ℹī¸
Poole J1855+10.8 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a large distance, above the mid-plane, affected by moderate extinction. It is catalogued as a massive, intermediate-age cluster (see Parameters). It is rarely studied in the literature.

⚠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.
