NGC 1819 is a lenticular galaxy in the constellation of Orion.[4] It was discovered on December 26, 1885, by American astronomer Lewis A. Swift.[7] This galaxy is located at a distance of 197.4 million light-years (60.53 Mpc) from the Milky Way,[3] and is receding with a heliocentric radial velocity of 4,483 km/s.[2]
The morphological classification of NGC 1819 is SB0 in the De Vaucouleurs system,[5] indicating this is a lenticular galaxy with a barred spiral organization. It is a gas-rich galaxy[8] with a circumnuclear ring structure that is undergoing intense star formation.[9]
Type Ia supernova[5] SN 2005el was discovered in NGC 1819 on September 19, 2005. It was positioned 39.0″ east and 22.6″ south of the nucleus.[10]
