Light year - Simple English Wikipedia, the free encyclopedia
A light year (symbol: ly) [1] is the distance that light travels in empty space in one year. Since the speed of light is about 300,000 km per second (about 186,000 miles per second), then a light year is 9.46 trillion kilometers (about 5.87 trillion miles), for AU, one light year is 63,241 AU. [2]
