Overview
ℹī¸
Collinder 135 is a rich, very dense object of very high C3 quality. Its parallax locates it at a very close distance, near the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption and mass parameters (see Parameters). It is very well-studied in the literature.

Note: This object shares a very small percentage of members with 3 later reported entries. See table with shared members information.
