A Light-Year is a measure of DISTANCE, not TIME. A light-year is how far light can travel in one year.
Light travels at 186,000 miles per second, or a little faster than 11 million miles per minute. In metric terms, the speed of light is a tad less than 300,000 km/sec.
1 light year is approximately 5.9 trillion miles, 20.5 light years would therefore be 20.5 times 5.9 trillion miles or about 120 trillion miles. traveling at 100,000 mph it would take about 137,000 years to travel the distance.
