Question

How do you measure the parallax angle of a star?

Answer 1

Parallax angle of a star is measured by the following method:-

Explanation:

`=>`Once a star is selected on which the scientists have to find the parallax angle,

`=>` Its position is thus recorded by them(Let it be A)

`=>`Again after 6 months, the position of the same star is measured which is sure to be different . This position of the star which is measured after the 6 months is the apparent position of the star.(Let it be B)

`=>`Thus an angle is formed between a A and B is the parallax angle of the star measured in arcseconds.
