It isn't because of its poor "thermal inertia". Thermal inertia is the time taken to absorb and conduct heat recieved from the Sun. Mercury's is poor because it lacks an atmosphere to keep the heat in. Although it has a poor thermal inertia, Mercury is hot. It can reach 660 degrees F (350 degrees C) at the equater.
