Overview

ℹ️

Markarian 50 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, very young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~3.11 kpc) differs significantly from the median photometric distance (~2.36 kpc).

Relatively close Moderate extinction Near-solar metallicity Very young
