__Mercury lies 57 910 000 kilometres (35 960 000 miles) from the Sun,__ and the first of the 4 __inner__ rock planets. Therefore the closest to the Sun and the smallest of planet the Solar System. (Pluto is not an official planet) Like all the planets in the Solar System, Mercury orbits the Sun, the movement caused by the Sun's gravity. __An orbit is a curved path of an object that travells around a larger heavenly body__. __Mercury orbits the Sun in 87.969 days,__ and rotates in 180 Earth days. Normally we refer to size in diameter and mass. The diameter is usually measured at the equator. Sometimes we can even calculate the volume.
