Answer :
To measure large distances across the universe, an appropriate unit would be a light year.
Here's why:
1. A light year is the distance that light travels in one year in the vacuum of space, which is about 5.88 trillion miles or 9.46 trillion kilometers. This unit is commonly used in astronomy to measure vast distances between celestial objects due to the immense scale of the universe.
2. Using a light year as a unit allows astronomers and scientists to accurately describe the vast distances between stars, galaxies, and other cosmic objects in a more convenient and meaningful way compared to using kilometers, miles, or astronomical units.
Therefore, the most suitable unit to measure large distances across the universe is a light year.
