The first exoplanet has been discovered by Subaru Strategic Program using the infrared spectrograph IRD on the Subaru Telescope (IRD-SSP). This planet, Ross 508b, is a super-Earth with about four times the mass of the Earth and is located near the habitable zone. Such a planet may be able to retain water on its surface, and will be an important target for future observations to verify the possibility of life around low-mass stars.
