Overview
ℹī¸
Trumpler 37 is a moderately populated, moderately dense object of high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, very young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is moderately studied in the literature.
