K2-155d is a potentially habitable Super-Earth exoplanet in the K2-155 system.[5] It is the outermost of three known planets orbiting around the K-type star K2-155 in the constellation Taurus.[6] It is one of 15 new exoplanets around red dwarf stars discovered by Japanese astronomer Teruyuki Hirano of the Tokyo Institute of Technology and his team.[1] The team used data from NASA's Kepler Space Telescope during its extended K2 "Second Light" mission. K2-155d orbits near the so-called habitable zone of its system, and has the potential to host liquid water.[7][5]
