NGC 6872, also known as the Condor Galaxy,[3] is a large barred spiral galaxy of type SB(s)b pec in the constellation Pavo. It is 212 million light-years (65 Mpc) from Earth.[3] NGC 6872 is interacting with the lenticular galaxy IC 4970, which is less than one twelfth as large.[2][3] The galaxy has two elongated arms with a diameter based on ultraviolet light of over 522,000 light-years (160,000 pc), and a D25.5 isophotal diameter of over 717,000 light-years (220,000 pc), making it the largest known spiral galaxy.[2][a][b] It was discovered on 27 June 1835 by English astronomer John Herschel.[4]
