Question

If a star has a parallax angle of 0.768" and the width of your pinky is about 1 degree, what percentage of your pinky will the parallax angle of the star make up?

Expert Solution

Introduction:

Parallax method is used to find the distances of distant objects. Parallax can be understood with easy scenarios. We see when moving in a car that trees moves fast but the distant mountains move very slowly. And the very distant moon or sun appears to be moving with us. It is all parallax.

We also know that there are 60 minutes in 1 degree.

$\begin{array}{rcl} 1^{o} & = & 60' (60 m i n u t e s) \\ 1' & = & 60'' (60 s e c o n d s) \end{array}$
