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.
