Overview

ℹ️

FSR 0031 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by very high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~2.25 kpc) differs significantly from the median photometric distance (~1.47 kpc).

Note: This object shares a significant percentage of members with 2 later reported entries. See table with shared members information.
