Overview
UPK 144 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a metal-rich, very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
