A recent new planet discovery has been reported in the nearby star system HD 176986, located about 91 light-years from Earth, where astronomers have identified a super-Earth-type exoplanet named HD 176986 d. The planet was discovered by an international research team using HARPS and HARPS-N spectrographs through the radial-velocity method, which detects subtle movements in a star caused by an orbiting planet. According to researchers, the planet has a minimum mass of around 6.8 times that of Earth and completes one orbit in approximately 61 days, placing it closer to its host star and making it too hot to be considered habitable. Scientists say the new planet discovery adds valuable data to the study of nearby multi-planet systems and helps improve understanding of how super-Earths form and evolve.
