Hephaestus

A "hot Mars," the iron-rich world is baked by Tau Ceti. The crust of the planet is a single plate, with the core having cooled off eons ago losing its magnetosphere. As a consequence, the planet lost most of its atmosphere to stellar winds. Hephaestus cannot become tidally locked to its star, due to tidal forces from its large moon, Arges. However, tidal forces from its star has slowed its rotational period such that it is tidally locked with its large moon.
