HD 155358 b
HD 155358 b is a gas giant planet that orbits the star HD 155358, located 142 light years away in the constellation Hercules. This planet orbits at a distance about 63% of distance between Earth and the Sun and has a moderate eccentricity. The planet mass is at least 89% of Jupiter, depending on inclination of the orbit and true mass of the star. It takes over half a year to orbit the star.
