HD 89744 b is aneccentric Jupiterextrasolar planet orbiting thestarHD 89744.[1]
In a simulation of a 10 million year span, this planet swept away all test particles "except for a narrow region near the 8:3 resonance". There can be no planets in this star's habitable zone. Observation has ruled out any planet over 0.7 Jupiter mass within a year period.[3]
