 It is situated in physical proximity to the galaxies NGC 4291 and NGC 4386, with X-ray emissions from the intervening gap indicating NGC 4319 and NGC 4291 may be interacting.NGC 4319 has a much higher proportion of ionized hydrogen compared to the Milky Way galaxy.In 1971, American astronomer Halton Arp noted what appeared to be a physical connection between NGC 4319 and Markarian 205, a quasi-stellar object with a much higher redshift.
