NGC 290 is an open cluster of stars in the southern constellation of Tucana. This cluster was discovered September 5, 1826 by Scottish astronomer James Dunlop.[6] It lies some 200,000 light years away from the Sun in the Small Magellanic Cloud galaxy.[7][2] The cluster is an estimated 30[4]–63[3] million years old and is around 65 light years across.[2][8]
