Overview
ℹī¸
Hogg 17 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is very well-studied in the literature.
Relatively close Moderate extinction Near-solar metallicity Intermediate age

Almeida et al. (2025)
