Overview

ℹ️

OC 0513 is a sparse, very dense object of intermediate C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is poorly studied in the literature.

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