A map of the Mid-Atlantic Ridge. The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent tectonic plate or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.
Since the distances are so large, we usually express them in Astronomical Units (AU). (An AU is the average distance from Earth to the Sun, about 150 million kilometers or 93 million miles.) The table below lists the distance of each planet from the Sun in AU. (Numbers were taken from this page.)
Average distance from the Sun is 142 million miles Perihelion distance 128.6 million miles, aphelion distance 160 million miles. Takes 687 days to orbit the Sun. Distance from Earth varies from 36 million miles (nearest planet after Venus) to over 250 million miles.
