Overview

ℹ️

Moitinho 1 is a moderately populated, very loose object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a low-mass, intermediate-age cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~4.39 kpc) differs significantly from the median photometric distance (~1.15 kpc).

Relatively close Moderate extinction Low mass Intermediate age
