NGC 406

NGC 406 is a spiral galaxy quite similar to the well known Whirlpool Galaxy, located some 65 million light-years away,[1] 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".[3] NGC 406 is about 60000 light-years across, roughly half the diameter of the Milky Way.
