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 average distance from the Earth to the Sun is about 150 million kilometers (93 million miles). This would be the radius of Earth's orbit, if it were a circle.* Doubling â¦ this number gives you a diameter of 300 million km., or 186 million mi.*It's actually an ellipse.he diameter of the Sun is 865,000 miles or 1.39 million in kilometers, while the Earth's diameter is 12, 765.2 kilometers.
