Overview

ℹ️

FSR 1053 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by low extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.60 kpc) differs significantly from the median photometric distance (~1.20 kpc).

Relatively close Low extinction Intermediate age
