Overview

ℹ️

FSR 1489 is a moderately populated, very dense object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a low-mass, old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.33 kpc) differs significantly from the median photometric distance (~1.21 kpc).

Note: This object shares a significant percentage of members with a later reported entry. See table with shared members information.
