Overview

ℹ️

FSR 1335 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a large distance, above 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 and mass parameters (see Parameters). It is well-studied in the literature.

Very distant Moderate extinction Near-solar metallicity Intermediate age

Almeida et al. (2025)
