Overview

ℹ️

FSR 1411 is a sparse, moderately dense object of high C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.03 kpc) differs significantly from the median photometric distance (~1.41 kpc).

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