Overview

ℹ️

FSR 1648 is a sparse, moderately dense object of very low C3 quality. Its parallax locates it at a moderate^* distance, above 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 (~2.44 kpc) differs significantly from the median photometric distance (~1.05 kpc).

Relatively close Low extinction Low mass Intermediate age
