Overview

ℹ️

CWNU 1836 is a sparse, very dense object of low C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by moderate extinction. It is catalogued as a metal-rich, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.

Relatively close Moderate extinction Metal-rich Intermediate age
