Overview

ℹ️

FSR 0101 is a rich, very dense object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by very high extinction. It is catalogued as a very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.52 kpc) differs significantly from the median photometric distance (~1.78 kpc).

Relatively close Very high extinction Very young
