This collage summarizes the research. Using the Okayama 188-cm Reflector Telescope and the observational instrument MuSCAT (See real photo on the bottom left.), researchers succeeded in observing the extrasolar planet K2-3d, which is about the same size and temperature as the Earth, pass in front of its host, the primary star blocking some of the light coming from the star (See artistic visualization at the top.), making it appear to dim (See real data on the bottom right.).
