Overview

ℹ️

FSR 0893 is a rich, loose object of high C3 quality. Its parallax locates it at a moderate distance, above 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 metallicity and mass parameters (see Parameters). It is moderately studied in the literature.

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