Overview
ℹī¸
ESO 559 13 is a poorly populated, very dense object of low C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is very well-studied in the literature.
Relatively close Low extinction Near-solar metallicity Intermediate age
