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.)
From antiquity up until the 1700s, estimates of the distance to the Sun differed widely from each other. Aristarchus of Samos working in the 3rd Century BC estimated that the Sun was about 20x further from the Earth than the Moon, or about 8 million km in modern units. This is about 20 times too small. Ptolemy, Copernicus, and Tycho Brahe all adopted a comparable value of 1210 Earth radii (also ~8 million km).
