NGC 152 is an open cluster in the constellation Tucana. It was discovered by John Herschel on September 20, 1835.^[4] It is located within the Small Magellanic Cloud.^[1]

NGC 152 is about 1.40 billion years old. Its estimated mass is, and its total luminosity is, leading to a mass-to-luminosity ratio of 0.31 /.^[5] All else equal, older star clusters have a lower luminosity for the same mass; that is, their mass-to-luminosity ratios are higher.^[5]
