What is a Light Years ?
A light year is not a unit of time — it’s a unit of distance.
It measures how far light travels in one year in space.
Speed of light = ~299,792,458 meters per second
1 light year = 9.461 × 10¹² kilometers (about 9.5 trillion km!)
In meters, it’s approximately 9.461 × 10¹⁵ meters
It’s used in astronomy to express massive distances between stars, planets, and galaxies.
