Explanation:
Light year is a unit of distance, not time.
Explanation:
- ✅ A light year is the distance that light travels in one year in a vacuum.
- ✅ Light travels at about 300,000 kilometers per second, so:
- ✅ 1 light year ≈ 9.46 trillion kilometers (9.46 × 10¹² km)
- ✅ Or ≈ 5.88 trillion miles
- ✅ Light year = unit of distance
- ✅ Julian year = unit of time
A light-year is a unit of distance, specifically used in astronomy to measure vast distances between celestial objects. It represents the distance that light travels in one Julian year (365.25 days) in a vacuum.
