Overview

ℹ️

Teutsch 48 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by high extinction. It is catalogued as a massive, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.69 kpc) differs significantly from the median photometric distance (~6.75 kpc).

Note: This object contains blue stragglers according to at least one source.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Very distant High extinction Massive Intermediate age Contains BSS
