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.)
We didn't know how big it was, and we didn't know how far away it was. We orbit the Sun at a distance of about 150 million kilometers. This number is actually an average, since we follow an elliptical path.At its closest point, the Earth gets to 147 million km, and at its most distant point, it's 152 million km.Distances in the Solar System are so vast that astronomers use this distance as a standard for measurement, and so the average distance from the Earth to the Sun is called an astronomical unit.e didn't know how big it was, and we didn't know how far away it was.
