Â­So to measure really long distances, people use a unit called a light year. Light travels at 186,000 miles per second (300,000 kilometers per second). Therefore, a light second is 186,000 miles (300,000 kilometers).
1 light year is 5.878625 trillion miles 5878625000000 miles in one light Year Divided by 36,373 (the speed of New Horizons) = 161620570.203 Hours Divide Hours by 24 to get days = 6734190.42513 Days Divide Days by 365 to get Years = 18449.8367812 Years. It will take New Horizons, our fastest space craft, 18,450 years to go ONE light year.
