Question

astronomers measure distances using very large units called light - years. which distance between celestial objects would most likely be measured in light - years?
○ distance between the sun and earth
○ distance between the moon and earth
○ distance between two stars in the same galaxy
○ distance between two planets in the same solar system

Explanation:

Light - years are used to measure extremely large distances in space. The distance between the Sun and Earth, the Moon and Earth, and two planets in the same solar system are relatively small (on an astronomical scale) and are usually measured in kilometers or astronomical units. The distance between two stars in the same galaxy is very large, so it is most likely measured in light - years.

Answer:

C. distance between two stars in the same galaxy
