A light-year is an enormous distance. 50,000 miles is such a small fraction of a light-year that it rounds down to 0.0000 for practical purposes in astronomy.

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.

50,000 miles is equivalent to driving around the Earth's equator more than twice.

This conversion is primarily used when discussing distances between stars or galaxies, which are measured in light-years due to their immense scale.
