The parallax of a heavenly body measured freo two points diametrically opposite on equator of earth is 2.0 minute.If radius of earth is 6400 km,calculate distance of heavenly body.

Angle = basis / distance

Here angle = 2 min = 2 * 2.9 * 10^-4 radian

basis = diameter of earth = 2* 6.4 * 10⁶ m

Therefore, distance = basis / angle

distance = 2 * 6.4 * 10⁶ / 2 * 2.9 * 10^-4

distance = 2.2 * 10¹⁰ m
