Recent numerical integrations, however, suggest that stable planetary orbits exist: within three AUs (four AUs for retrograde orbits) of either Alpha Centauri A or B in the plane of the binary's orbit; only as far as 0.23 AU for 90 - degree inclined orbits; and beyond 70 AUs for planets circling both stars (Weigert and Holman, 1997).
An Earth - type planet could have liquid water in a stable orbit centered around 3.5 AU (within a predicted habitable zone ranging between 2.3 and 4.8 AUs) from Star A — between the orbital distances of the Main Asteroid Belt and Jupiter in the Solar System (NASA Stars and Exoplanet Database).
Kepler has identified thousands of planets with stable orbits, and some within the range to support liquid water.
