NGC 1533 is a barred lenticular galaxy with faint spiral structure in the constellation Dorado and the seventh brightest member of the Dorado Group and 1°[3] off the group's center.[2] It is surrounded by a vast arc or ring of H I which is connected to IC 2038 and IC 2039.[2] The ring orbits around 32 kpc from the center.[3][b] It is typical of lenticular galaxies in that star formation is weak in NGC 1533.[2] Using both the surface brightness fluctuation (SBF) and globular cluster luminosity function (GCLF) methods, its distance was estimated in 2007 to be 19.4 ± 1.1 Mpc and 18.6 ± 2.0 Mpc respectively.[2] Averaging these together gives a distance of around 19 million parsecs or 62 million light-years from earth.[a] In 1970, a supernova was detected in NGC 1533.[4]
NGC 1533 was discovered by John Herschel on December 5, 1834.
