Overview

ℹ️

PHOC 10 is a poorly populated, moderately 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 metal-poor, young cluster, but with a large variance across recent sources for the distance parameter (see Parameters). It is poorly studied in the literature.
