Overview

ℹ️

OC 0685 is a poorly 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 metal-rich, very young cluster (see Parameters). It is rarely studied in the literature.

⚠️ Warning: This is likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.
