Arp 104, also known as Keenan's system, is entry 104 in Halton Arp's Atlas of Peculiar Galaxies catalog for spiral galaxy NGC 5216 and globular galaxy NGC 5218.[1] The two galaxies are joined by a bridge of galactic material spanning 22 000 light years.[1][2]
In 1790 William Herschel discovered the galaxies, and in 1926 they were studied by Edwin Hubble.[1] In 1935 Philip C. Keenan first published a paper about the bridge connecting the galaxies,[1][3] which was rediscovered in 1958 at the Lick and Palomar observatories.[1][2][4]
