Overview

ℹ️

FSR 1234 is a poorly populated, moderately dense object of intermediate C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by moderate 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 (~5.69 kpc) differs significantly from the median photometric distance (~1.71 kpc).

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