Overview
ℹī¸
NGC 2264 is a very rich, very dense object of high C3 quality. Its parallax locates it at a close distance, near 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 absorption parameter (see Parameters). It is very well-studied in the literature.

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