What are examples in which it would be appropriate to use light years as a unit of measure?

Light years are typically used to measure vast astronomical distances, such as the distance between stars or galaxies. For instance, the nearest star system, Alpha Centauri, is about 4.37 light years away from Earth. Additionally, light years can be used to express the distances to celestial objects like nebulae or quasars, helping astronomers convey the immense scales of the universe in a comprehensible way.
