This galaxy is known to contain two counter-rotating populations of stars. That is, one set of stars is rotating in the opposite direction with respect to the other.

NGC 3593 is a lenticular galaxy located in the constellation Leo. It has a morphological classification of SA(s)0/a,[3] which indicates it is a lenticular galaxy of the pure spiral type.[4] Despite this, it has a large amount of hydrogen, both in its molecular (H
2) and atomic (H) form.[5] It is a starburst galaxy, which means it is forming new stars at a high rate. This is occurring in a band of gas surrounding the central nucleus. There is a single arm, which spirals outward from this ring.[6] It is frequently but not consistently identified as a member of the Leo Triplet group.[7]

This galaxy is known to contain two counter-rotating populations of stars—that is, one set of stars is rotating in the opposite direction with respect to the other.[5] One means for this to occur is by acquiring gas from an external source, which then undergoes star formation. An alternative is by a merger with a second galaxy. Neither scenario has been ruled out. The age of the lower mass, counter-rotating population is younger by about 1.6 ± 0.8 Gyr than the primary star population of the galaxy.[6]

A dynamical study found that there is likely a supermassive black hole (SMBH) at the center of NGC 3593. The mass of the SMBH is between 3.0×105 and 4.3×106 solar masses.[5]
