Overview

ℹ️

FSR 0902 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a relatively close^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~1.96 kpc) differs significantly from the median photometric distance (~1.24 kpc).

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