One light-year is equal to about 5.88 trillion miles. So, 5 light-years is approximately 29,393,964,248,787 miles.

Astronomers use light-years because the distances to stars and galaxies are so enormous that using miles would result in incredibly large and difficult-to-manage numbers.

5 light-years is equivalent to about 47,302,562,390,000 kilometers.

Currently, with our fastest spacecraft, traveling 5 light-years would take tens of thousands of years. It's a distance far beyond our current capabilities.
