Answer is Right!
Answer is Wrong!
The correct answer is: C. distance between bodies in the universe.
A light year is a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 Ã 1012 km (nearly 6 trillion miles). It is used to measure distances to stars and other objects outside the Solar System.
The speed of satellites, ships, and rockets are typically measured in kilometers per hour (km/h) or miles per hour (mph).
