Question

How many earth years are in 1 light year?

Answer 1

An earth year is a unit of time.

A light year is a measure of distance.

Explanation:

A light year is the distance light will travel in a vacuum over the period of one (earth) year.

Since light travels at about `186,300` miles per second, with `86,400` seconds per day and about `365` days per year, that works out at about:

`186300xx86400xx365 ~~ 5,875,000,000,000` miles.
