The Sun is not a fixed distance from Mars. Mars has an elliptical orbit, so the distance between the Sun and Mars varies.

Here's a breakdown:

* Average Distance: Mars is about 1.52 AU (astronomical units) from the Sun on average.

* Closest Approach (Perihelion): At its closest point, Mars is about 1.38 AU from the Sun.

* Furthest Point (Aphelion): At its furthest point, Mars is about 1.67 AU from the Sun.

Converting AU to Light-years:

* 1 AU is approximately equal to 0.00001581 light-years.

Therefore:

* Average Distance in Light-years: 1.52 AU * 0.00001581 light-years/AU = 0.000024 light-years

* Closest Approach in Light-years: 1.38 AU * 0.00001581 light-years/AU = 0.000022 light-years

* Furthest Point in Light-years: 1.67 AU * 0.00001581 light-years/AU = 0.000026 light-years

Important Note: Light-years are a unit of distance used for extremely long distances in space, and the distance between the Sun and Mars is relatively small. It's more common to express this distance in AU.
