Overview

ℹ️

FSR 0087 is a rich, dense object of high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, metal-rich, intermediate-age cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.59 kpc) differs significantly from the median photometric distance (~1.17 kpc).

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