Answer 1

Answer:

Parallax method helps us to measure the diameter of any planet. It depends on how far the planet is for it you should first know the parallax of that particular planet and then depending on it the diameter of the planet is determined. Depending on how close it is to Earth.

Explanation:

Parallax is the slight or perceived change in the position of a planet when measured from two different places from the planet you are measuring. The final derived parallax of the planet help us to assume it's distance from Earth(say) and also it's diameter.
