Question

How to determine the distance of different stars from the Earth?ORExplain the method to determine the distance of a planet from the earth and the diameter of the planet.

Answer 1

Answer:

Explanation:

The distance between these things is determined by trignometry

Answer 2

Dear Student,

● Parallax method for measuring distance and diameter of planet -

Parallax method is used for measuring the distance & diamters of far stars/objects.

Let the planet of diameter d be viewed from distance x on earth surface. It makes an angle θ between the two eyes.

Then, the angle of parallax is given by -

θ = d / x

Diameter of the planet will be thus given by -

d = θ × x

If you want to know distance of a planet from earth,

x = d / θ

Hope I was useful...
