With the help of this method we measure the distance of planets and stars which are very far away from Earth. To understand this method, we have to do an exercise.

This happens because there are a few centimeters between your eyes and when you look at that thumb with separate eyes, the angle of vision formed on your eye with that thumb changes and this phenomenon is called parallax. And we call the change in the position of the body by looking with a separate eye as parallax shift.
Repeat the same activity by bringing your thumb closer to your nose and then …………
