The order of magnitude of the diameter of the earth is (diamtere of the earth is `1.28xx10^(7)m`)

What is the order of magnitude of radius of earth ?

The radius of the earth and the radius of orbit around the sun are 6371 km and 149 xx 10^(6) km respectively. The order of magnitude of the diameter of the orbit is greater than that of earth by

Estimate the order of magnitude of surface area of earth.

The approximate diameter of the sun is times the diameter of Earth.

The moon subtends an angle of 57 minutes at two diametrically opposite points on earth. Calculate the distance of the moon from the earth. Given, diameter of earth =1.276xx10^7 m .
