Mercury boasts an orbit that is the most elliptical of all of the planets, stretched out from a perfect circle. When it is closest to the sun, it is only 29 million miles (47 million km), but at its farthest, the distance to Mercury is 43 million miles (70 million km).
Astronomers convert large distances such as these to astronomical units. An astronomical unit (AU) is 93 million miles, which is the average distance from the sun to Earth. In this regard, Mercury's average distance from the sun is 0.387 AU. To put this into perspective, Neptune's average distance from the sun is 30.1 AU. The closest Mercury comes to Earth during its orbit is 48 million miles.
