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.
The Tarantula Nebula is a large H II region in the Large Magellanic Cloud (LMC), forming its south-east corner.
NGC 1872 is an open cluster within the Large Magellanic Cloud in the constellation Dorado. It was discovered by James Dunlop in 1826.
NGC 346 is a young open cluster of stars with associated nebula located in the Small Magellanic Cloud (SMC) that appears in the southern constellation of Tucana. It was discovered August 1, 1826 by Scottish astronomer James Dunlop. J. L. E. Dreyer described it as, "bright, large, very irregular figure, much brighter middle similar to double star, mottled but not resolved". On the outskirts of the cluster is the multiple star system HD 5980, one of the brightest stars in the SMC.
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. It lies some 200,000 light years away from the Sun in the Small Magellanic Cloud galaxy. The cluster is an estimated 30–63 million years old and is around 65 light years across.
NGC 265 is an open cluster of stars in the southern constellation of Tucana. It is located in the Small Magellanic Cloud, a nearby dwarf galaxy. The cluster was discovered by English astronomer John Herschel on April 11, 1834. J. L. E. Dreyer described it as, "faint, pretty small, round", and added it as the 265th entry in his New General Catalogue.
NGC 1903 is a star cluster in the Large Magellanic Cloud in the constellation Dorado. It was discovered in 1834 by John Herschel with an 18.7-inch reflecting telescope.
NGC 1755 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. It has a diameter of 2.6′ and an apparent magnitude of 9.9. It was discovered by James Dunlop in 1826.
NGC 176 is an open cluster around 3.5 million light-years away in the constellation Tucana. It is located within the Small Magellanic Cloud. It was discovered on August 12, 1834 by John Herschel.
NGC 220 is an open cluster located approximately 210,000 light-years from the Sun in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on August 12, 1834 by John Herschel.
NGC 330 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on 1 August, 1826 by James Dunlop. It was described by Dreyer as "a globular cluster, very bright, small, a little extended, stars from 13th to 15th magnitude." At an aperture of 31.0 arcseconds, the apparent V-band magnitude is 9.60, but at this wavelength, it also has 0.36 magnitudes of interstellar extinction.
NGC 361 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on September 6, 1826 by James Dunlop. It was described by Dreyer as "very very faint, pretty large, very little extended, very gradually brighter middle." At an aperture of 31.0 arcseconds, its apparent V-band magnitude is 12.24, but at this wavelength, it has 0.40 magnitudes of interstellar extinction.
NGC 1978 is an elliptical shaped globular cluster or open cluster in the constellation Dorado. It is located within the Large Magellanic Cloud. It was discovered by James Dunlop on November 6, 1826. At an aperture of 50 arcseconds, its apparent V-band magnitude is 10.20, but at this wavelength, it has 0.16 magnitudes of interstellar extinction. It appears 3.9 arcminutes wide. NGC 1978 has a radial velocity of 293.1 ± 0.9 km/s.
NGC 2002 is an open cluster located in the Dorado constellation and is part of the Large Magellanic Cloud. It was discovered by James Dunlop on September 24, 1826. Its apparent magnitude is 10.1, and its size is 2.0 arc minutes.
N11 is the brightest emission nebula in the north-west part of the Large Magellanic Cloud in the Dorado constellation. The N11 complex is the second largest H II region of that galaxy, the largest being the Tarantula Nebula. It covers an area approximately 6 arc minutes across. It has an elliptical shape and consists of a large bubble, generally clear interstellar area, surrounded by nine large nebulae. It was named by Karl Henize in 1956.
NGC 1984 is an open cluster associated with an emission nebula, it is located in the constellation Dorado in the Large Magellanic Cloud. It was discovered by John Herschel on 16 December 1835. The apparent magnitude is 9.9 and its size is 1.50 by 1.20 arc minutes.
NGC 1970 (also known as ESO 56-SC127) is a bright open cluster and emission nebula in the Dorado constellation in the Large Magellanic Cloud. It was discovered by John Herschel on January 31, 1835. Its apparent size is 8.0. It is commonly known as the Tulip Nebula.
NGC 2266 is an open cluster in the constellation Gemini. Its apparent size is 5 arc minutes. Its distance is 3,400 parsecs (11,000 ly). It was discovered by German-British astronomer William Herschel on 7 December 1785.
NGC 1712, also known as GC 942, JH 2685, and Dunlop 112 is an open cluster in the constellation of Dorado. It is relatively small, and is located inside the Large Magellanic Cloud. NGC 1712 was originally discovered in 1826 by James Dunlop, although Herschel rediscovered it in 1834. Nine variable stars have been discovered in it so far, with three suspected to be binary systems.
NGC 2004 is an open cluster of stars in the southern constellation of Dorado. It was discovered by Scottish astronomer James Dunlop on September 24, 1826. This is a young, massive cluster with an age of about 20 million years and 23,000 times the mass of the Sun. It has a core radius of 2.85 ± 0.46 pc (9.3 ± 1.5 ly). NGC 2004 is a member of the Large Magellanic Cloud, which is a satellite galaxy of the Milky Way.
