A light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). It's a unit of astronomical distance.

There are approximately 5.88 trillion miles (9.46 trillion kilometers) in one light-year.

A light-year represents an incredibly vast distance, covering trillions of miles. 10,000 miles is a relatively short distance on a human or planetary scale, making it negligible when compared to interstellar distances.

While mathematically possible, the result is a very small fraction (0.0000 light-years) because 10,000 miles is an extremely tiny distance compared to the immense scale of a light-year. It's more for conceptual understanding than practical calculation.
