After an eleven year observing campaign , we present the combined visual–spectroscopic orbit of the formerly unremarkable bright star HR 7345 ( HD 181655 , HIP 94981 , GJ 754.2 ) .
Using the Separated Fringe Packet ( SFP ) method with the CHARA Array , we were able to determine a difficult to complete orbital period of 331.609 \pm 0.004 days .
The 11 month period causes the system to be hidden from interferometric view behind the Sun for 3 years at a time .
Due to the high eccentricity orbit of about 90 % of a year , after 2018 January the periastron phase will not be observable again until late 2021 .
Hindered by its extremely high eccentricity of 0.9322 \pm 0.0001 , the double-lined spectroscopic phase of HR 7345 is observable for 15 days .
Such a high eccentricity for HR 7345 places it among the most eccentric systems in catalogs of both visual and spectroscopic orbits .
For this system we determine nearly identical component masses of 0.941 \pm 0.076 M _ { \odot } and 0.926 \pm 0.075 M _ { \odot } as well as an orbital parallax of 41.08 \pm 0.77 mas .
