NGC 3799 is a bar-spiral galaxy with an active nucleus of the Hubble type SBb in the constellation Leo north of the ecliptic . It is estimated to be 145 million light years from the Milky Way and about 35,000 light years across. Together with NGC 3800 , it forms the interacting galaxy pair ARP 83 or KPG 296 .
Halton Arp listed the galaxy in his catalog of special galaxies due to the closely spaced galaxy. This galaxy belongs to the class spiral galaxies with a large companion of high surface brightness on one arm (Arp catalog) .
The object was discovered on April 21, 1832 by the astronomer John Herschel .
