Overview
HXHWL 20 is a moderately populated, very dense object of 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 near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.
Note: This object shares a moderate percentage of members with a later reported entry. See table with shared members information.
