Question

❤this pic is for my dear friends❤ ☺my question is what is parallax method explain ☺

Answer 1

Parallax is a method of measuring distance to an object. Similar to how our binocular vision helps us determine distance, the direction to a distant point is slightly different from two separate observation positions. If the distance between the observation positions is known, and the angle between them can be measured, it is a matter of simple geometry to calculate the distance to the object. It is a relatively simple concept but is one of the most important for making astronomical  observations.

Answer 2

Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. 

When viewed from "Viewpoint A", the object appears to be in front of the blue square. When the viewpoint is changed to "Viewpoint B", the objectappears to have moved in front of the red square.
