NGC 5579 is a barred spiral galaxy of the Hubble type SABcd in the constellation Bootes in the northern sky . It is estimated to be 164 million light years from the Milky Way and about 90,000 light years in diameter.
Immediately south of NGC 5579 is the Lenticular Galaxy PGC 214249 . Together they form a presumably interacting pair cataloged as Arp 69 . Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class spiral galaxies with a small companion of high surface brightness on one arm (Arp catalog) .
The type IIb supernova SN 2006ss was observed here.
The object was discovered by William Herschel on May 1, 1785 .
