HD 154345
HD 154345 (Gliese 651) 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.
Planetary system.
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 ("
HD 154345 b
HD 154345 b, is a Jupiter-sized extrasolar planet orbiting the star HD 154345.
Discovery.
Wright et al. discovered the planet in March 2006 using the radial velocity method to detect the small wobbling movement of the star caused by the gravity of the planet. The discovery was confirmed in May 2007.
Characteristics.
The planet has a mass at least slightly less than that of Jupiter. It orbits its parent star at the distance of 4.18 AU. Its orbital period is about
