I apologize for the error in my previous response. The correct value for one light-year is approximately 5.88 trillion miles or 9.46 trillion kilometers, not 9.46 * 10^15.
To clarify the calculation:
One light-year is the distance that light travels in one year. The speed of light in a vacuum is approximately 186,282 miles per second (or about 299,792 kilometers per second).
To find the distance traveled in one year, we multiply the speed of light by the number of seconds in a year:
Speed of light = 186,282 miles per second (or about 299,792 kilometers per second) Seconds in a year ≈ 31,536,000 (60 seconds * 60 minutes * 24 hours * 365 days)
Distance in one year = Speed of light * Seconds in a year Distance in one year ≈ 5.88 trillion miles (or about 9.46 trillion kilometers)
So, one light-year is approximately equal to 5.88 trillion miles or 9.46 trillion kilometers.
