The distance between the Sun and Mars varies greatly because Mars has an elliptical orbit.

Here are some key points:

* Average Distance: The average distance between the Sun and Mars is approximately 142 million miles (228 million kilometers).

* Perihelion (Closest Point): At its closest point to the Sun (perihelion), Mars is about 128 million miles (206 million kilometers) away.

* Aphelion (Farthest Point): At its farthest point from the Sun (aphelion), Mars is about 155 million miles (249 million kilometers) away.

So, the exact distance depends on where Mars is in its orbit.
