Light travels approximately 5.88 trillion miles (9.46 trillion kilometers) in one year. This distance is known as a light-year, which is the distance light travels in a vacuum over the course of one Julian year (365.25 days)
. To break it down:
- Light speed is about 186,000 miles per second (300,000 kilometers per second)
- There are about 31,536,000 seconds in one year.
- Multiplying the speed of light by the number of seconds in a year gives the total distance light travels in a year, which is about 9.46 trillion kilometers or 5.88 trillion miles
This immense distance is used in astronomy to measure the vast scales between stars and galaxies, making it easier to comprehend the enormity of the universe
