NGC 7752 and NGC 7753 are a pair of galaxies approximately 272 million light-years away in the constellation Pegasus. They were discovered by R. J. Mitchell on 22 November 1854.[3]
NGC 7753 is the primary galaxy. It is a barred spiral galaxy with a small nucleus. NGC 7752 is the satellite galaxy of NGC 7753. It is a barred lenticular galaxy that is apparently attached to one of NGC 7753's spiral arms. They resemble the Whirlpool Galaxy (M51A) and its satellite NGC 5195 (M51B).
