NOTE: This animation attempts to relate the orbits (and possible habitable zones) of Stars A, Ba, and Bb in the 85 Pegasi 3 system to their respective centers of mass. To enlarge the display, the orbits have been arbitrarily rotated by 45 degrees. The initial display shows the ABab System's known orbital tilt (at an inclination of 49°) from the visual perspective of an observer on Earth. However, the orbital inclination of any planet that may be discovered someday in this star system would likely be different from those of the habitable zone orbits depicted here.
Star A and the binary pair Bab have a fairly close, average separation of about 10.3AUs and an orbital period of around 26.3 years. The stars in the Bab pair may have an average separation within two AUs (of a semi-major axis) with an orbital period lasting less than four years.
