NGC 7619 is an elliptical galaxy located in the constellation Pegasus.[2] NGC 7619 and NGC 7626[3] are the dominant and brightest members of the Pegasus galaxy cluster.[4] Both of them were discovered by William Herschel on September 26, 1785.[5]

The radial velocity of this galaxy was measured in 1929 and found to be double that of any galaxy observed at that time.[6] The measurement was consistent with the extrapolated value predicted by Edwin Hubble; a distance-velocity relation that would later become known as Hubble's Law.[7]
In 1970, a type Ia supernova was detected within NGC 7619; it was subsequently designated SN 1970J.[8]
