How many light-years does light travel in 1 second?

Answer (2)

There are none at all. A "light year" is a distance, not a time. It's the distance that light travels through vacuum in one year ... about 5.875 trillion miles.

Light travels approximately 299,792 kilometers in one second. This speed is crucial for understanding astronomical distances, such as light-years, which are the distance light travels in one year, approximately 9.46 trillion kilometers. Therefore, the distance light travels in one second is a small fraction of a light-year.
