Gliese 163 c (/ˈɡliːzə/) or Gl 163 c is said to be a potentially habitable exoplanet,[3][4] orbiting within the habitable zone of M dwarf star Gliese 163.[5]

The parent star is 15.0 parsecs (approximately 49 light-years, or 465 trillion kilometers) from the Sun, in the constellation Dorado. Gliese 163 c is one of three planets discovered in the system. With a mass at least 7.2 times that of the Earth,[3][4] it is classified as a super-Earth (a planet of roughly 1 to 10 Earth masses).[4][6]
