NGC 7716 is an intermediate spiral galaxy located in the constellation Pisces. Its speed relative to the cosmic microwave background is 2,201 ± 26 km/s, which corresponds to a Hubble distance of 32.5 ± 2.3 Mpc (∼106 million ly).[1] NGC 7716 was discovered by British astronomer John Herschel in 1831.[2]

The luminosity class of NGC 7716 is II and it has a broad HI line.[3] According to the SIMBAD database, NGC 7716 is a candidate galaxy for the active galaxy classification.[4]

To date, twelve non-redshift measurements give a distance of 32.442 ± 5.854 Mpc (∼106 million ly), which is within the Hubble distance values.[5]
