Overview

ℹ️

FSR 0236 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 high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~1.77 kpc) differs significantly from the median photometric distance (~1.23 kpc).

Note: This object shares a small percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
