Known planets
g Infrared speckle interferometric searches for companions with a mass between 50 an 80 Jupiter-masses at 1-10 AUs and 100-1,000 AUs of Luyten's Star also have not been able to confirm the existence of such an object

Habitable zone
g Distance from the star where an Earth-type planet would be "comfortable" with liquid water is centered around 0.15 AUs, where its orbital period would be competed in less than 42 days. At such a close in orbit, however, the rotation of the planet may become tidally locked
