Kapteyn-b’s orbit of 48 days is very close to an integer fraction (143/48= 2.979) making it extremely suspicious. To quote [lightly edited due to suspect grammar] the paper about the star’s planets: GJ 273b is a super-Earth with a minimum mass of 2.89±0.26 Me (Earth masses) with an … Prominent in the sky will be Luyten's innermost planet, which whizzes around the star in just 4.7 days at a bit more than one-third distance of Luyten b. Luyten's Star / ˈ l aɪ t ən z / (GJ 273) is a red dwarf in the constellation Canis Minor located at a distance of approximately 12.36 light-years (3.79 parsecs) from the Sun.It has a visual magnitude of 9.9, making it too faint to be viewed with the unaided eye. Earth is trying to communicate with aliens around Luyten's star - and could hear back in 25 years. It will exhibit phases like Venus.
