NGC 6040 is a spiral galaxy located about 550 million light-years away[3] in the constellation Hercules.[4] NGC 6040 was discovered by astronomer Édouard Stephan on June 27, 1870.[5] NGC 6040 is interacting with the lenticular galaxy PGC 56942.[6][7] As a result of this interaction, NGC 6040's southern spiral arm has been warped in the direction toward PGC 56942.[2] NGC 6040 and PGC 56942 are both members of the Hercules Cluster.[2][8]

NGC 6040 was classified in the 1966 Atlas of Peculiar Galaxies by Halton Arp, who listed it as Arp 122.[9] However, Mr. Arp mistakenly identified NGC 6040 as NGC 6039, which is not part of any Arp object.[5]
