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]

Contents

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]

Supernova

One supernova has been observed in NGC 7619: SN 1970J (Type Ia, mag. 14.5) was discovered by Leonida Rosino on 24 September 1970. [8] [9] [10]
