If the moon attracts the earth, why does the earth not move towards the moon?

Statement I : Earth continuously attracts the moon towards its centre and yet the moon does not move towards the centre of earth. Statement II : The gravitational force of atteraction between the moon and earth provides the necessary centripetal force.

According to Newton's law of gravitation, every object attracts every other object. Thus, if the earth attract an apple towards itself, the apple also attracts the earth towards itself with the same force. Why then does the apple fall toward the earth, but the earth does not move towards the apple ?

The Earth is acted upon by the gravitational force of attraction due to the sun. They why does the Earth not fall towards sun?

Since the Moon is gravitational attracted to the Earth, why does it not simply crash into the Earth?

The earth revolves round the sun because the sun attracts the erth. The sun also attracts the moon and this force is about twice as large as the attraction of the earth on the mon. Why does the moon not revolve round the sun? Or does it?

The acceleration due to gravity on the moon is (1^(th))/(6) that on the earth. If the earth and the moon are assumed to have the same density, then the radius of the moon is

The radius and acceleration due to gravity of the moon are 1/4 and 1/5 that of the earth, the ratio of the mass of the earth to mass of the moon is
