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 89% of Jupiter (making this mass type II), though, only a minimum mass is known, and this planet may be more massive than Jupiter, depending on inclination of the orbit and true mass of the star. It takes over half a year to orbit the star.

The temperature of this planet would speculated to be about 295 K, similar to that of Earth. This planet is Sudarsky Class II (water jovian). If this planet has any Earth-like moons, it may provide habitable environment to support life.
