NGC 718


NGC 718 is a intermediate spiral galaxy in the constellation of Pisces. Its velocity with respect to the cosmic microwave background is, which corresponds to a Hubble distance of. Additionally, one non-redshift measurement gives a similar distance of. 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.
A star-forming disk has been detected around the core of NGC 718. The size of its semi-major axis is estimated at.

Supermassive black hole

Based on measurements of the near-infrared K-band luminosity of the galaxy's bulge, NGC 718 has a supermassive black hole with a mass of .

NGC 676 group

NGC 718 is a member of a small group of three galaxies known as the NGC 676 group. The other two galaxies are NGC 676 and NGC 693.

Intermediate-luminosity red transient

One intermediate-luminosity red transient has been observed in NGC 718:AT 2019udc was discovered by the Distance Less Than 40 Mpc Survey on 4 November 2019. This object had initially been classified as a luminous blue variable.
