Question

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

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

Explanation:

A parsec is a unit used in astronomy. It is specifically for measuring distances between stars and other celestial objects. The distance between Earth and the Moon is usually measured in kilometers or miles. The distance between the North and South Poles is on - Earth measurement (about 20,000 km along the meridian). The distances between planets in the solar system are often measured in astronomical units (AU) or kilometers. But for inter - stellar (between stars) and distances to other far - off celestial objects, parsec is a more appropriate unit.

Answer:

stars and other celestial objects
