NGC 362 (Caldwell 104) is a globular cluster located in the constellation Tucana in the Southern Hemisphere, slightly north of the Small Magellanic Cloud. It was discovered on August 1, 1826 by James Dunlop.[5] It is visible to the naked eye in dark skies, and is an impressive sight in a telescope, although it is somewhat overshadowed by its larger and brighter neighbour 47 Tucanae.[6]

The stars of NGC 362 have an average metallicity higher than the stars in most globulars. This implies that NGC 362 is a relatively young globular cluster.[6] It also has an overabundance of binary stars, and an exceptionally tight core 13 light-years in diameter.[6] The orbit of NGC 362 is highly eccentric, taking it to within 3,260 light-years of the galactic center.[6]
