Wolf 1069 is a red dwarf star located 31.2 light-years (9.6 parsecs) away from the Solar System in the constellation of Cygnus. The star has 17% the mass and 18% the radius of the Sun, a temperature of 3,158 K (2,885 °C; 5,225 °F), and a slow rotation period of 150–170 days. It hosts one known exoplanet called Wolf 1069 b which could possibly sustain life.[4]
