Light year is nothing but an astronomical metric used to compute the speed and distance of light traveling through space in one year. Other units of measure used to quantify distances that are greater than a light-year include a kiloparsec (1,000 parsecs, or 3.26 million light-years), a megaparsec (one million parsecs, or 3.26 billion light-years) and even gigaparsecs (one billion parsecs, or 3.26 trillion light-years)! To give you a great example of how far a light year actually is, it will take Voyager 1 (NASAs longest-lived spacecraft) over 17,000 years to reach 1 light year in distance traveling at a speed of 61,000 kph. If you wanted to travel 100 trillion light years away, you could make the journey in 62 years.
