Overview
ℹī¸
VDB 113 is a rich, moderately dense object of very high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a very massive, near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is moderately studied in the literature.
