Question

In parallax method we always have a stationary star to refer to......how do we measure tge distance of that stationary star??Please give a genuine answer

Its not on google.....​

Answer 1

Answer:

The apparent motion and the change in angle are so small that they are imperceptible to the naked eye. In fact, the first stellar parallax was only measured in 1838 by German astronomer Friedrich Bessel. Applying the tangent trigonometric function to the measured parallax angle and the distance traveled by the Earth around the sun gives the distance to the star in question.

hope it helps u mark it as branlist

Answer 2

DETERMINATION OF DISTANCE OF A STAR BY PARALLAX METHOD:

distance = length of arc/ parallatic angle

= length of arc/ angle 1 + angle 2

(we take angle 1 and 2 because here we split the whole angle into its two constitutes)

The angle which we are using here is angle subtended by the star to the given points of earth .
