ℹ️

Juchert 18 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by moderate extinction. It is catalogued as an old cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.
