NGC 718 is an intermediate spiral galaxy in the constellation of Pisces. Its velocity with respect to the cosmic microwave background is 1,450±22 km/s, which corresponds to a Hubble distance of 69.7 ± 5.0 Mly (21.38 ± 1.54 Mpc). Additionally, one non-redshift measurement gives a similar distance of 69.80 Mly (21.400 Mpc). It was discovered by German-British astronomer William Herschel on 13 December 1784.
NGC 718 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
