The distance from the Sun to Mars varies because Mars has an elliptical orbit.

Here are some ways to describe the distance:

* Average distance: 228 million kilometers (142 million miles)

* Closest point (perihelion): 206.6 million kilometers (128.4 million miles)

* Farthest point (aphelion): 249.2 million kilometers (154.6 million miles)

It's important to note that these distances are just averages and can change slightly due to the gravitational influences of other planets.
