Overview

ℹ️

OC 0546 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is rarely studied in the literature.

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