Solution
A light year is the unit of distance. It is the distance that light travels in one year. Here's a step-by-step explanation:
- Light travels at a speed of approximately 300,000 kilometers per second (186,000 miles per second).
- In one minute, light can travel about 18 million kilometers (11 million miles).
- In one hour, light can travel about 1.08 billion kilometers (671 million miles).
- In one day, light can travel about 26 billion kilometers (16 billion miles).
- In one year, light can travel about 9.46 trillion kilometers (5.88 trillion miles).
So, a light year is about 9.46 trillion kilometers or 5.88 trillion miles. It's a very large distance, and it's used to measure distances in space.
