NGC 433 is an open cluster in the northern constellation of Cassiopeia, located at a distance of 6,500 light years from the Sun.[1] It was discovered on September 29, 1829, by John Herschel, and was described by John Dreyer as "cluster, small, a little compressed."[4] The cluster is considered on the poor side, with only 12 stars above magnitude 16.[5] It has a linear diameter of 26.3 ly, with around 479 times the mass of the Sun and an age of 65 million years.[2]
