NGC 3800 is a barred spiral galaxy of the Hubble type SBb / P in the constellation Leo north of the ecliptic . It is estimated to be 145 million light years from the Milky Way and about 90,000 light years in diameter. Together with NGC 3799 , 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 8, 1784 by the astronomer Wilhelm Herschel .
