NGC 1533 is a barred lenticular galaxy with faint spiral structure in the constellation Dorado. The seventh-brightest member of the Dorado Group and 1° off the group's center,{{cite journal | author = DeGraaff, Regina Barber | author2 =Blakeslee, John P. | author3 =Meurer, Gerhardt R. | author4 =Putman, Mary E. | title = A Galaxy in Transition: Structure, Globular Clusters, and Distance of the Star-Forming S0 Galaxy NGC 1533 in Dorado | journal = The Astrophysical Journal | date = December 2007 | volume = 671 | issue = 2 | pages = 1624–1639 | doi = 10.1086/523640 | bibcode=2007ApJ...671.1624D| arxiv =0710.0893| s2cid =14312626 }} it is surrounded by a vast arc or ring of H I which is connected to IC 2038 and IC 2039. The ring orbits around 32 kpc from the center.{{Cite book | author1 = Ryan-Weber, Emma|author1-link=Emma Ryan-Weber | author2 =Webster, Rachel | author3 =Bekki, Kenji | title =The IGM/Galaxy Connection | chapter =Galactic Recycling: The HI Ring Around NGC 1533 | series =Astrophysics and Space Science Library | editor = Jessica L.

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. Averaging these together gives a distance of around 19 million parsecs or 62 million light-years from earth. In 1970, a supernova was detected in NGC 1533.{{cite journal | author = Evans, R. | title = Supernova in NGC 1533. | journal = IAU Circ. | date = 1970 | issue = 2279 | pages = 1 | bibcode = 1970IAUC.2279....1E

NGC 1533 was discovered by John Herschel on December 5, 1834.

Notes

average(19.4 ± 1.1, 18.6 ± 2.0) = ((19.4 + 18.6) / 2) ± ((1.12 + 2.02)0.5 / 2) = 19.0 ± 1.1 35 kpc calculated assuming a distance of 21 Mpc converts to a distance of 32 (35 ÷ 21 × 19) kpc for the current distance estimate of 19 Mpc
