Question

1. a parsec is a unit of measurement for calculating absolute and apparent magnitude, and it also expresses the distances between ____.

○ the planets in the solar system
○ the north and south poles
○ earth and the moon
○ stars and other celestial objects

Explanation:

A parsec is a large unit of length used in astronomy to measure vast distances in space, particularly between stars and other celestial objects. The distances between planets in the solar system, Earth and the moon, or the North and South Poles are much smaller and measured with other units (like astronomical units or kilometers), while parsecs are suited for interstellar/celestial object distances.
