Overview

ℹ️

FSR 1530 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is poorly studied in the literature.

Note: This object contains blue stragglers according to at least one source.

Distant High extinction Massive Intermediate age Contains BSS
