Beta Tucanae B is a magnitude +13.5 M3-type star which is a close companion to Beta1, being 2.4 arcseconds, or at least 100 AU away.

Beta2's companion, the 6th magnitude Beta Tucanae D, is another A-type star which is separated by approximately 0.38 arcseconds (16 AU) from Beta2.

It is not clear how tightly Beta3 Tucanae is gravitationally bound to the rest of the β Tucanae system, but all the stars have similar distances from Earth and have the same proper motion on the sky, indicating they are gravitationally influencing each other to some degree.

Both components of the binary system are white A-type main sequence stars and they have apparent magnitudes of +5.8 and +6.0.

Beta3 Tucanae has an infrared excess, suggesting the presence a debris disk around the primary star.
