Overview

ℹ️

FSR 1105 is a moderately populated, very loose object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, well below the mid-plane, affected by high extinction. It is catalogued as a low-mass, intermediate-age cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~3.17 kpc) differs significantly from the median photometric distance (~1.58 kpc).

Relatively close High extinction Low mass Intermediate age
