Overview

ℹ️

FSR 1255 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by low extinction. It is catalogued as a low-mass, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~5.78 kpc) differs significantly from the median photometric distance (~1.02 kpc).

Relatively close Low extinction Low mass Intermediate age
