Callisto is a moon of Jupiter, not a star. Therefore, it doesn't have its own light years.

However, we can calculate the distance from Callisto to the Sun based on its distance from Jupiter:

* Callisto's average distance from Jupiter: 1,882,700 kilometers

* Jupiter's average distance from the Sun: 778.5 million kilometers

Adding these distances:

1,882,700 km + 778,500,000 km = 780,382,700 km

Converting to light years:

1 light year is approximately 9.461 trillion kilometers.

Therefore, Callisto's average distance from the Sun is approximately 0.0000824 light years.
