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).
A light year is 9.4605284 Ã 10^15 m, or 9.4605284 Ã 10^12 km. So it'd take you about 237123803 hours, which works out at 27069 years or over 27 millenia. And the nearest star to Earth is 4 light years away. This is why most scientists think we'll never achieve interstellar travel.
