The distance from Mars to the Sun varies because Mars' orbit is elliptical, not circular.

Here's a breakdown of the distances:

* Average Distance:

* Miles: 141.6 million miles (227.9 million kilometers)

* Perihelion (Closest to the Sun):

* Miles: 128.4 million miles (206.6 million kilometers)

* Aphelion (Farthest from the Sun):

* Miles: 154.6 million miles (249.2 million kilometers)
