Overview
ℹī¸
ASCC 16 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a very close distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is very well-studied in the literature.

Note: This object shares a large percentage of members with 2 later reported entries. See table with shared members information.

Almeida et al. (2025)
Mass determination: intermediate fit. Isochrone match: good fit. Silver sample.
