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

0.5 light-year is approximately equal to 15,520,013,123,359,580 feet.

While light-years are standard for astronomical distances, converting to feet can help visualize these vast distances in a more familiar, albeit very large, unit.

Astronomers primarily use light-years, parsecs, or astronomical units (AU). Converting to feet is mostly for educational purposes or specific comparative contexts.
