Overview
ℹī¸
FSR 1500 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a large* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~6.93 kpc) differs significantly from the median photometric distance (~1.38 kpc).

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

Relatively close Moderate extinction Massive Near-solar metallicity Intermediate age
