HD 154345
HD 154345 is a G-type dwarf star located in northern Hercules. It is not visible to the naked eye since it is below +6.50 magnitude, but using binoculars it is an easy target.In 2006, a long-period, wide-orbiting planet was observed by radial velocity, and published in May 2007, gaining the designation HD 154345 b.
The complete observation of its nine-year orbit rules out any interior planets of minimum mass greater than 0.3 Jupiter. The star rotates at an inclination of 50 degrees relative to Earth. It is probable that the planet shares that inclination. It has been called a "Jupiter twin".
The system's habitable zone is centered at.754 AU and is narrower than the Sun's.
