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.)
Introduction. Earth revolves around the Sun in an elliptical orbit with a mean eccentricity of 0.0167. As a result, Earthâs distance from the Sun (center-to-center) varies with mean values of 0.9832899 AU (147,098,074 km) at perihelion (closest) to 1.0167103 AU (152,097,701 km) at aphelion (most distant).xtreme Perihelion and Aphelion. The extremes in Earth's perihelion and aphelion distances for the 21 st Century are listed below. Earthâs mean distance from the Sun at perihelion is 0.9832899 AU (147,098,074 km). Earthâs mean distance from the Sun at aphelion is 1.0167103 AU (152,097,701 km).
