Overview
ℹī¸
VDB 85 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is well-studied in the literature.

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