Overview

ℹ️

Majaess 133 is a rich, moderately dense object of very high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by high extinction. It is catalogued as a very massive, near-solar metallicity, very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is rarely studied in the literature.

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