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.)
The exact distance between Earth and the Sun varies with its position in its orbit, which is elliptical. The average distance (the mean distance) between the Earth and the Sun is about 150 million kilometers (93 million miles). The average distance from the Earth to the Sun is also called 1 astronomical unit (or AU). This is established as 149, 597, 870.7 kilometers (92,955,887.6 miles).
