A radar antenna sends out a short radio pulse and then waits for it to echo off an airplane or other similar target. While it's waiting, it counts the number … Web17 jan. 2024 · It would take a spacecraft approximately 10,000 years to travel one light year. This is because the speed of light is roughly 300,000 kilometers per second and it takes about 9.5 trillion kilometers to make up one light year. So if you were traveling at the speed of light it would still take you 10,000 years!
