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.)
1 The Earth is much closer to the Sun than it is to Jupiter.  Distances from the Sun are measured in Astronomical Units (AU). The Earth is the standard unit, and is one AU from the Sun, so an AU equals 150 million kilometres (93 million miles), the distance of the Earth from the Sun.
