- The smallest distance is a yard, which is a unit of length commonly used in the US. 
- A kilometer is longer than a yard and is used as a measure of distance in most countries. 
- An astronomical unit (AU) is the average distance from the Earth to the Sun and is much larger than a kilometer.
- A light-year is the distance that light travels in one year and is much larger than an AU. Therefore, the correct order is III, I, IV, II.
