The seventh-brightest member of the Dorado Group and 1°[9] 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]{{Ref_label|B|b|none}} As is typical of lenticular galaxies, 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.{{Ref_label|A|a|none}} In 1970, a supernova was detected in NGC 1533.[4] NGC 1533 was discovered by John Herschel on December 5, 1834.
