NGC 7714 is a spiral galaxy in the constellation Pisces. Its velocity with respect to the cosmic microwave background is 2430 ± 26 km/s, which corresponds to a Hubble distance of 116.9 ± 8.3 Mly (35.85 ± 2.54 Mpc).[2] In addition, five non-redshift measurements give a distance of 92.24 ± 8.69 Mly (28.280 ± 2.664 Mpc).[5] It was discovered by British astronomer John Herschel on 18 September 1830.[6]
NGC 7714 and NGC 7715 are interacting galaxies.[4] The pair are included in Halton Arp's Atlas of Peculiar Galaxies, listed as Arp 284.[7] NGC 7714 appears to be a highly distorted spiral, possibly a barred spiral galaxy. NGC 7715 is of uncertain type, probably an edge-on spiral or an irregular galaxy.[3]
