Mercury's distance from the sun varies because its orbit is elliptical.

Here are the key distances:

* Average distance: 57.9 million kilometers (35.9 million miles)

* Perihelion (closest point): 46 million kilometers (28.6 million miles)

* Aphelion (farthest point): 69.8 million kilometers (43.4 million miles)

To convert these distances to meters, multiply by 1000:

* Average distance: 57,900,000,000 meters

* Perihelion: 46,000,000,000 meters

* Aphelion: 69,800,000,000 meters
