Light travels at a speed of 186,000 miles a second or 700 million miles an hour. For scale, the distance from the Earth to the Moon is about 239,000 miles. This seems pretty fast and indeed theory says that nothing can travel faster than the speed of light.
The length of time it takes to go from:
Earth to Moon: 1.3 seconds
Earth to Sun: 8.3 minutes
Sun to Pluto: 5 hours 40 minutes
Our solar system to the nearest star(Alpha Centauri): 4.3 years
Across our galaxy: 100,000 years
To the Andromeda Galaxy: 2.5 million years
