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 Sun is the nearest star to Earth. The distance between the Sun and the Earth varies as the Earth revolves around the Sun. The average is called 1 Astronomical Unit. Its value is 149,597,871 kilometers. Nearest star is sun ..!! :) Since earth and sun distance in varying in elliptical orbit. Average distance is 150 million Kilometres.
