Overview

ℹ️

OC 0259 is a poorly populated, moderately dense object of low C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is rarely studied in the literature.

Note: This is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry, and a very small percentage with at least one entry reported in the same catalogue. See table with shared members information.
