The distance between the stars and the Earth is measured in which unit?

The distance between the stars and the earth is measured in light years.
The distance between stars and Earth is so immense that conventional units like kilometers or miles become impractical. Astronomers use special units like light-year to express these vast distances more conveniently. A light-year is the distance light travels in one year, approximately 9.461 trillion kilometers.This unit based on the speed of light, provide a more manageable scale for expressing the enormous distances in the vastness of space, making it easier for scientists to work with and comprehend the cosmic scales involved.

Hence, the correct option is "light year".
