Question

what is parallelex method​

Answer 1

Answer:

Parallax (from Ancient Greeks (parallaxis), meaning 'alternation') is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.[1][2] Due to foreshortening, nearby objects show a larger parallax than farther objects when observed from different positions, so parallax can be used to determine distances.

Answer 2

Answer:

The apparent angular displacement of a celestial body due to its being observed from the surface instead of from the center of the earth.

Explanation:

How astronomers use parallax method :-

• 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.
