Overview

ℹ️

NGC 281-east is a poorly populated, very loose object of very low C3 quality. Its parallax locates it at a moderate distance, below the mid-plane. It is catalogued as a cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 23 years.

Note: This is very likely a unique object, which shares a very 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=0.91) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
