Overview
ℹī¸
Skiff J0507+30.8 is a rich, very dense object of high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is very well-studied in the literature.

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