A meteoric impact is likely responsible for it's Weird Terrain, which is near a crater filled with lava known as the Caloris Basin. Due to a liquid metal dynamo at its core, this body possesses a weak magnetic field that is only 1% the strength of the Earth's. Perturbations in the orbit of this planet supported Einstein's theory of relativity and the MESSENGER spacecraft recently made a flyby of it. For 10 points, name this smallest planet that is also closest to the sun.
