Which unit is used to measure the very large distances between stars and other celestial bodies?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Light year
A light year is the distance light travels in one year, about \(9.46\times10^{12}\) km, and is used for distances between stars. A nautical mile is used at sea and in the air, and a galactic year is a period of time, not a distance.
