Overview

ℹ️

CWNU 2990 is a poorly populated, very dense object of intermediate C3 quality. Its parallax locates it at a very large^* distance, above the mid-plane, affected by very high extinction. It is catalogued as a very young cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~12.87 kpc) differs significantly from the median photometric distance (~21.38 kpc).
