HD 79968 has been known for some time as a spectroscopic binary, but the orbit of this system remained unknown until now. Our observations, carried out at Observatoire de Haute-Provence with the CORAVEL spectrometer, lead to the following orbital elements: P=30.50253days; T=2448008.696JD; ω= 65^o.8; e=0.187; K₁=40.3km/s; K₂=45.3km/s; V₀=+25.3km/s; a₁sin i=16.6Gm; a₂sin i=18.7Gm; M₁sin³i=1.00M_☉; M₂sin³i=0.89M_☉. The ratio of the correlation dip areas indicates a magnitude difference {DELTA} m_B∼0.9 between the components. The observational data (M_1,2sin³i, {DELTA}m, M_V, B-V and the spectrum) are consistent with spectral types G3-4V and G9V for the primary and secondary components respectively. The M₁sin³i value, one solar mass, suggests strongly that i should be near 90^o. This detached system (a=50R_☉) thus might be an eclipsing one.
