expression of calculating distance of
the star from the earth.​

Answer 1

Answer:

Parallax method is used for measuring too long distances ex= distance from earth to moon , Mars ,Jupiter etc.

Explanation:

theta(in radian) = arc (with center C ) /radius

Answer 2

Answer:

It is a method which is use for measuring the distance between two planeta and star.

let have e.g distance between moon & earth

first take two succesive point on earth which is (arc).

The disrance between two planet are show by radius (rl =d

and angle made from ( tetta)

our formula of is s =tetta×radius

radius=arc÷tetta

d=arc÷tetta
