caption_attribution_description: English: An artist’s impression showing a newly discovered Jupiter twin gas giant orbiting the solar twin star, HIP 11915. The planet is of a very similar mass to Jupiter and orbits at the same distance from its star as Jupiter does from the Sun. This, together with HIP 11915’s Sun-like composition, hints at the possibility of the system of planets orbiting HIP 11915 bearing a resemblance to our own Solar System, with smaller rocky planets orbiting closer to the host star.
context_page_description: HIP 11915 b is an exoplanet orbiting the solar twin star HIP 11915 about 190 light-years from Earth in the constellation Cetus. It is notable as the first exoplanet to be discovered with an orbit and mass similar to that of Jupiter, 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. The exoplanet was found by using the radial velocity method, where periodic Doppler shifts of spectral lines of the host star suggest an orbiting object.
context_section_description: HIP 11915 b is an exoplanet orbiting the solar twin star HIP 11915 about 190 light-years (57 parsecs, or nearly 1.798×10¹⁵ km) from Earth in the constellation Cetus. It is notable as the first exoplanet to be discovered with an orbit and mass 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. The exoplanet was found by using the radial velocity method, where periodic Doppler shifts of spectral lines of the host star suggest an orbiting object.
