how far can light travel in one year

The distance light can travel in one year is known as a light-year. Light travels at a speed of approximately 299,792 kilometers per second (km/s) or 186,282 miles per second.

To calculate the distance light can travel in one year, we need to multiply the speed of light by the number of seconds in a year.

There are 60 seconds in 1 minute.
There are 60 minutes in 1 hour.
There are 24 hours in a day.
There are 365.25 days in a year (accounting for leap years).

So, the total number of seconds in a year is:
60 seconds/minute x 60 minutes/hour x 24 hours/day x 365.25 days/year = 31,536,000 seconds/year

Now, let’s multiply the speed of light by the number of seconds in a year:
299,792 km/s x 31,536,000 s/year ≈ 9,461,000,000 km/year

Therefore, light can travel approximately 9.461 billion kilometers (or 5.88 billion miles) in one year. This distance is known as a light-year, which is a unit of distance used to measure the vast scales of our universe.
