NGC 1712, also known as GC 942, JH 2685, and Dunlop 112 is an open cluster in the constellation of Dorado. [2] [3] It is relatively small, and is located inside the Large Magellanic Cloud. [4] NGC 1712 was originally discovered in 1826 by James Dunlop, although Herschel rediscovered it in 1834. [4] Nine variable stars have been discovered in it so far, with three suspected to be binary systems. [5]

Dorado is a constellation in the Southern Sky. It was named in the late 16th century and is now one of the 88 modern constellations. Its name refers to the dolphinfish, which is known as dorado in Spanish, although it has also been depicted as a swordfish. Dorado contains most of the Large Magellanic Cloud, the remainder being in the constellation Mensa. The South Ecliptic pole also lies within this constellation.
