3. A 12.8 day year ?? That puts it mighty close to its primary ... or a really small primary.

Something about the name Gliese12 rang a bell -- it is a very nearby red dwarf, not visible to the naked eye.

Along with the planets of TRAPPIST-1, Gliese 12 b is one of the nearest known relatively temperate transiting exoplanets, and so is a promising target for the James Webb Space Telescope to determine whether it has retained an atmosphere.[7] Gliese 12 b orbits slightly closer than the inner edge of its star's habitable zone, with an insolation between those of Earth and Venus.[6] Its equilibrium temperature, assuming zero albedo, is 315 K (42 °C; 107 °F); if it has an atmosphere, the surface temperature would be greater than this.[5]

A bit warm, but not completely incompatible with life, particularly with enough water.
