How lengthy is a Light-Year?

The light-year is a measure of distance, not time. It is the full distance the a beam that light, moving in a right line, travel in one year. To obtain an idea the the dimension of a light-year, take the one of the planet (24,900 miles), lay it the end in a straight line, main point the size of the heat by 7.5 (the corresponding distance is one light-second), then location 31.6 million comparable lines end to end. The resulting distance is almost 6 trillion (6,000,000,000,000) miles!
