The New General Catalogue of Nebulae and Clusters of Stars (abbreviated as NGC) is a catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, known as the NGC objects. It is one of the largest comprehensive catalogues, as it includes all types of deep space objects, including galaxies, star clusters, emission nebulae and absorption nebulae.

NGC 406 is a spiral galaxy quite similar to the well known Whirlpool Galaxy, located some 65 million light-years away, in the southern constellation of Tucana (the Toucan) and discovered in 1834 by John Herschel. It is described in the New General Catalogue as "faint, very large, round, very gradually a little brighter middle". NGC 406 is about 60000 light-years across, roughly half the diameter of the Milky Way.
