Leave a Reply Cancel reply. are in a light-year. How far does light travel in 6 years? Doing the math, a Light-year is 9.46 trillion km, or 5.88 trillion miles.Trillion is 10^12. Note that this value is considered exact, since the meter is actually (as of 1983) defined in terms of the light second. The distance that light travels in a year is called a light year. Light travels at 300,000 km per second so dividing one by the other gives you 500 seconds â eight minutes and twenty seconds. A light-year is the distance that light travels in one year. A car is 2.0 km west of a traffic light at t = 0 and 5.0 km east of the light at t = 6.0 min. Better still, this service is absolutely FREE. How far does light travel a year? The star nearest Earth is the Sun. The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second. More specifically, a light year is defined as the distance that a photon would travel, in free space and infinitely far away from any gravitational or magnetic fields, in 20 miles per hour = 29.3 feet per second. 1 Meter: Distance light travels in 1/299 792 458 of a second in vacuum. answer in scientific notation.
