History

The galaxy NGC 7753 was discovered on 12 September 1784 by the German-British astronomer William Herschel with his 18.7 inch reflecting telescope. He cataloged it as II 213. The discovery of the neighboring small galaxy NGC 7752 by RJ Mitchell had to wait until 22 November 1854. He observed the galaxy with the large 72 inch reflecting telescope of his employer William Parsons, 3rd Earl of Rosse. [277]

In Halton Arp's 1966 Atlas of Peculiar Galaxies, the two galaxies are listed as Arp 86, a spiral galaxy with large companions of high surface brightness, similar to M 51 / NGC 5195 (Arp 85). [199]

Physical Properties

The two galaxies are in gravitational interaction and are about 70 Mpc apart. [145, 439]
