Question

What is light year??​

Answer 1

$\huge\underline \mathfrak \blue{Answer:-}$

Light travels at a speed of about 3 lakh km per second. The distance covered by a ray of light in a year or 365 days is called a light year.

Answer 2

A light year (symbol: ly) is the distance that light travels in empty space in one year. Since the speed of light is about 300,000 km per second (about 186,000 miles per second), then a light year is about 10 trillion kilometers (about 6 trillion miles).
