How long does light take to cross a distance?
The time light, or anything moving at a share of its speed, takes to cover a distance.
Time to cross
8 min 19 s
Light takes 8 min 19 s to cross 149,597,900,000 m.
- Time in seconds
- 499 s
Try an example
How it is worked out
t = distance_m / (speed_share * c)Where the numbers come from
Keep in mind
The time scales with one over the speed: at half the speed of light the crossing takes twice as long. A time over a day is shown in days and hours.
