HIP 11915 b is a candidate exoplanet orbiting the solar twin star HIP 11915 about 175 light-years (54 parsecs) from Earth in the constellation Cetus. It is notable as its orbit and mass are similar to that of Jupiter (essentially, a "Jupiter analog"), suggesting that its system may be similar to that of the Solar System. It orbits its star at a distance of approximately 4.8 AU.
