Overview

ℹ️

FSR 1500 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~6.93 kpc) differs significantly from the median photometric distance (~1.38 kpc).

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