NGC 152 is an open cluster in the constellation Tucana. It was discovered by John Herschel on September 20, 1835.[5] It is located within the Small Magellanic Cloud.[1]

NGC 152 is about 1.40 billion years old. Its estimated mass is 2.5×104 M, and its total luminosity is 8.0×104 L, leading to a mass-to-luminosity ratio of 0.31 M/L.[3] All else equal, older star clusters have a lower luminosity for the same mass; that is, their mass-to-luminosity ratios are higher.[3]
