Overview
MCM 91 is a sparse, very dense object of low C3 quality. Its parallax locates it at a relatively close* distance, near the mid-plane. It is catalogued as a cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 13 years.
(*): The parallax distance estimate (~1.95 kpc) differs significantly from the median photometric distance (~1.33 kpc).
Note: This object shares a very small percentage of members with a later reported entry. See table with shared members information.
