M46 is a circular open cluster with an overall magnitude of 6.1 at a distance of approximately 5400 light-years from Earth. The planetary nebula NGC 2438 is superimposed; it is approximately 2900 light-years from Earth. M46 is classified as a Shapley class f and a Trumpler class III 2 m cluster. This means that it is a rich cluster that appears distinct from the star field; however, it is not at its center. The cluster's stars, numbering between 50 and 100, have a moderate range in brightness.[1] | M46 is a circular open cluster with an overall magnitude of 6.1 at a distance of approximately 5400 light-years from Earth.
