NGC 1755 (also known as ESO 56-SC28)[3] is an open star cluster in the Large Magellanic Cloud in the Dorado constellation. It is about 120 light years across and due to its size could be a globular cluster.[2] It has a diameter of 2.6′ and an apparent magnitude of 9.9.[3] It was discovered by James Dunlop in 1826.[2]
