LEDA / PGC 71505 (also NGC 7674A ) is a spiral galaxy with extended ones of the Hubble type Sa in the constellation Pegasus in the northern sky . It is estimated to be 402 million light years from the Milky Way and about 35,000 light years in diameter. Together with NGC 7674 it forms the interacting galaxy pair Arp 182 and together with NGC 7675 and PGC 71507 the galaxy quartet HCG 96 .
Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class of narrow filament galaxies .
The Type Ia supernova SN 2000A was observed here.
