Expert Answer

Step 1

With the help of telescope we can look the planet from the earth surface. Using the parallax angle method, we can calculate the diameter of planet.

In the figure,

Telescope is on the earth surface at point A.

D = closest distance of planet from earth surface.

d = diameter of planet.
