- Theta2_Crucis abstract "Theta2 Crucis (θ2 Cru / Theta2 Crucis) is a spectroscopic binary star in the constellation Crux. This pair of stars complete an orbit every 3.4280 days and they have a low orbital eccentricity that is close to 0.0. Theta2 Crucis is located at about 750 light-years from the Sun.The system has a combined mean apparent magnitude of +4.72m. Since a member of the system is a β Cephei-type variable star, the magnitude is not fixed but varies slightly between +4.70m and +4.74m. The period of this variability is 0.0889 days. The system is categorized as is a blue-white subgiant with a stellar classification of B2 IV.".
