Overview

ℹ️

FSR 1149 is a poorly populated, loose object of high C3 quality. Its parallax locates it at a moderate distance, near 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 absorption parameter (see Parameters). It is poorly studied in the literature.

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