TX Leonis is a triple star, consisting of magnitude 8.1 star (component B) separated by 2 arc seconds from the brighter eclipsing pair (components Aa and Ab). Although orbital motion has not been detected, the companion shares a common proper motion with the primary star and is at approximately the same distance.

Both stars comprising the eclipsing binary are main sequence stars. Of those two stars, star Aa has been assumed to be 8 times more luminous than star Ab, although newer estimates give the luminosities as 83 L☉ and 6 L☉ respectively.
