Wolf 1061 c is an exoplanet orbiting within the habitable zone of the red dwarf star Wolf 1061 in the constellation Ophiuchus, about 14.1 light-years from Earth. At the time of discovery, it was the closest known potentially habitable exoplanet to Earth, though several closer ones have since been found.[5][6] It is the second planet in order from its host star in a triple planetary system, and has an orbital period of 17.9 days. Wolf 1061 c is classified as a super-Earth exoplanet as its mass is between that of Earth and the ice giants.
