Overview

ℹ️

FSR 0519 is a moderately populated, dense object of very high C3 quality. Its parallax locates it at a moderate^* distance, above 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 mass parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~2.94 kpc) differs significantly from the median photometric distance (~2.09 kpc).

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