NGC 1316 , also known as Fornax A and ARP 154 known is a lenticular galaxy with active galaxies core from the Hubble type SB0 in the constellation Fornax the southern sky , an estimated 73 million light-years of the Milky Way is removed.
With an apparent magnitude of 8.4 mag, NGC 1316 is the brightest member of the Fornax galaxy cluster, which is about 70 million light-years away, and is one of the brightest galaxies that are not in the Local Group or one of the immediately neighboring galaxy groups . Its angular extent is 11.0 '× 7.2', from which a diameter of about 255,000 light years can be derived. This makes it more than twice the size of our Milky Way . As one of the brightest radio sources in the sky, it is also known as Fornax A in the usual way for large radio galaxies .
Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class of galaxies with internal absorption .
The galaxy NGC 1317 is located about 6 'north of NGC 1316 and forms an interacting pair with it . Seen from Earth in close proximity to Fornax A ( NGC 1316 ) there are three other galaxies, which are referred to as NGC 1316A , NGC 1316B and NGC 1316C .
The object was discovered on September 2, 1826 by James Dunlop , who listed the object as number 548 in his catalog of newly discovered nebulae and star clusters in the southern hemisphere.
