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.)
There is a unit for measuring the distance from the earth to the sun known as an astronomical unit. This is 149,597,870,691Km (~93 million miles) plus or minus 30Km. You can use an astronomical unit to compare distances against the distance between the earth and sun e.g the distance between the sun and Mars is 1.52 AU.
