The moon does not fall onto the earth despite the attraction between the earth and the sun because of
A
The usn’s opposing attraction
B
The centrifugal reaction
C
A gravitational repulsion
D
The fixed orbit in which the moon rotates
Explanation: 

Detailed explanation-1: -The moon revolves around the earth in a similar way but due to the velocity with which the moon got hooked onto the earth’s gravity keeps it from falling onto the earth. This keeps the moon in a pretentious orbit around the earth even though it is moving further away from our planet by an ever so little margin.

Detailed explanation-2: -Because both the Earth and the Moon are attracted to the Sun with practically the same acceleration. The Earth and the Moon end up moving together and are not separated by the force of the Sun.

Detailed explanation-3: -However, moon revolves around the earth in a circular motion because of the centripetal force acting of on it. In absence of centripetal force, the moon will not be able to follow a circular path and would move in a straight line tangential to the orbit of the moon.

Detailed explanation-4: -Earth has invisible pulling power called gravity. In fact, our planet isn’t the only place with gravity. Every object in the universe-stars, planets, moons, even you-has gravity. Gravity is a force of attraction between all objects.
