Overview

â„šī¸
Ryu 144 is a sparse, dense object of low C3 quality. Its parallax locates it at a moderate distance, near the mid-plane. No fundamental parameter values are available for this object. It is rarely studied in the literature, with no articles listed in the last 7 years.

Note: This is a unique object, which shares a very small percentage of members with at least one previously reported entry. See table with shared members information.

âš ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=0.96) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

No fundamental parameters
