What are some facts about light years?
Nov 7th, 2014

light years is a measure of distance, not of time as most people think. This measurement is used for very long distances related to space, like measuring the distance between planets or galaxies and their components (astronomical distances).

Its magnitude is the distance light can travel in one year, with its velocity 3,000,000 km/s.
