Match each distance to the appropriate category according to the unit of measurement that best describes the size scale of each distance.
The unit of measurement:
- kilometer (km)
- astronomical unit (AU)
- light-year (ly)
Distances:
- distance between Quebec and London
- radius of Mercury
- distance between Mercury and Neptune
- distance between the sun and the star Proxima Centauri
- distance between Neptune and the center of the Milky Way
- distance between galaxies

Answer :

kilometers (km): Mercury's radius and the distance between Québec and London.

Mercury and Neptune's distance is measured in astronomical units (AU).

Light-year (ly): The separation between the sun and the star Proxima centauri, neptune and the galactic center, and the separation between galaxies.

What does an astronomical unit mean?

The average distance between Earth and the Sun, or roughly 93,000,000 miles, is referred to as an astronomical unit. Then, if we say an object is 35 AU from the Earth, we mean it is 35 times farther away from the Earth than the Earth is from the Sun, or 35 times 93 million miles.
