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 Julian year
