Overview
ℹ️
FSR 0296 is a moderately populated, very dense object of low C3 quality. Its parallax locates it at a moderate* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

(*): The parallax distance estimate (~3.51 kpc) differs significantly from the median photometric distance (~2.50 kpc).

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

Relatively close Moderate extinction Near-solar metallicity Intermediate age
