Overview

ℹ️

UPK 94 is a poorly populated, moderately dense object of high C3 quality. Its parallax locates it at a close distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is moderately studied in the literature.

Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
