NOTE: This animation attempts to relate the orbits (and possible habitable zones) of Stars A and B in the 36 Ophiuchi AB system to their common center of mass. Although the initial display shows the system's actual orbital tilt (at an inclination of 99.6°) from the visual perspective of an observer on Earth, the orbital inclination of any planet that may be discovered someday around either star would likely be different from those of the habitable zone orbits depicted here. (At about at over 4,400 to 5,400 AUs away, 36 Ophiuchi C is too far away to depict here.)

Based on an average parallax (0.1675") incorporating Hipparcos data, stars A and B are separated "on average" by about 88 AUs (of a semi-major axis) in a highly eccentric orbit (e= 0.922) that swings between seven and 169 AUs and takes around 570 years to complete (Irwin et al, 1996 -- "Orbit 4") and (Peter Brosche, 1960).
