About this world
Wolf 1061 b is an Earth-sized planet orbiting Wolf 1061, a cool red dwarf (type M3.5) 14 light-years from Earth. It is about 1.2 times the size of Earth (its size estimated from its mass), with at least 1.9 Earth masses (a minimum, measured by radial velocity). It completes an orbit every 4.89 days at 0.037 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 461 K (188 °C): far too hot for liquid water on its surface. By the "cosmic shoreline", its star has probably stripped its atmosphere away, leaving bare rock.
It was discovered in 2015 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum. Wolf 1061 has 3 known planets; the others are Wolf 1061 c and Wolf 1061 d.
