In 2006, the long-period, wide-orbiting planet was observed by
radial velocity , and published in May 2007, gaining the designationHD 154345 b .The complete observation of its nine year orbit rules out any interior planets of minimum mass ("m" sin"i") greater than 0.3 Jupiter. The system's
habitable zone is centred at .754 AU and is narrower than Sol's. [Square root of stellar luminosity.] Assuming that the system is oriented edge-on to Earth (inclination ~90, so that the real mass of the planet is about equal to Jupiter's), HD 154345 b does not come close enough to the habitable zone to disrupt the orbits of potentialEarth -like planets in the system.References
