Wolf 1069 b is an Earth-sized planet orbiting the red dwarf star Wolf 1069. Being located in the habitable zone of its star, Wolf 1069 b is considered a potentially habitable planet, as well as the sixth-closest Earth-mass planet orbiting within its star's habitable zone.[5] The minimum mass of the planet, as measured by the radial velocity method, is 1.26 ME, while its radius is estimated at 1.08 R🜨.[1] The equilibrium temperature of Wolf 1069 b is -23 °C.[2][3]
