A Saturn-mass planet was detected around the red dwarf star by J. A. Johnson and associates in 2010. It has a
minimum mass 32.8% of
Jupiter's mass and is located 1.15
astronomical units from its star in eccentric orbit (e=0.3). Assuming a luminosity of 4.5% that of the
Sun, the
habitable zone is located at , thus the planet should be as cold as if it were located at from a Solar-like star. Also accounting for different
periastron and
apastron positions of 0.8 and respectively, the planet could likely show seasonal temperature changes.
Debris disk Using results from the
Herschel Space Observatory survey of 21 late-type stars carried out in 2010, a debris disk was discovered between approximately 6 and . The disk was not detected at 22μm by NASA's
Wide-field Infrared Survey Explorer so therefore it is likely to be below 100 Kelvin and similar to the
Kuiper belt. The disk was marginally resolved, appearing very asymmetric, and so is probably consistent with being closer to edge-on, rather than face-on, in its inclination. ==References==
