Answer:

1. light years

2.it varies

Answer 2

Explanation:

a) Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star's apparent movement against the background of more distant stars as Earth revolves around the sun.

b )The diameter of the moon is to be calculated by the parallax method, by assuming two points serving as the diameter ends and define the angle made by it on earth and assume the parallel shortest distance. Apply tangent and trigonometry to infer the finding
