No, it is not. "For every action there is an equal and opposite reaction". The 70kg person is pulling just as hard on the Earth as the Earth is on the 70kg person, i.e. about 686 N.
Newton's third law states that for every action, there is an equal and opposite reaction. So, while the Earth exerts a force on an object that is equal to the object's weight, the object exerts an equal force in the opposite direction on Earth. This is why you can feel the ground pushing up on you when you stand on it.
With its smaller mass, the Moon exerts only about 1/6 the gravity as the Earth, so objects would weigh just one-sixth of their Earth weight on the lunar surface. This is why the astronauts were able to float up off the surface as they walked there, even in their heavy spacesuits.
The force of gravity that Earth exerts on objects in our solar system causes those objects to be attracted towards Earth. This force keeps objects like planets, moons, and spacecraft in orbit around Earth and maintains the stability of the solar system.
The gravitational force between two objects decreases with distance. If the Moon were moved to half its current distance from the Earth, the gravitational force it exerts on the Earth would increase by a factor of four (2^2), since force is inversely proportional to the square of the distance.
The Moon is considerably smaller than the Earth. Its volume is about 2% of the Earth's. Its mass is only about 1.2% of the Earth's. Its surface gravity is about 1/6 that of the Earth.

Every planetary body (including the Earth) is surrounded by its own gravitational field, which exerts an attractive force on all objects. (http://en.wikipedia.org/wiki/Gravitation). Because of gravity of earth we stay on the earth.
The person in space exerts a force of 850 N on the earth. The fact that the person is weightless has no bearing on this question. Ever since Newton enunciated his three laws of motion we have known that action and reaction are equal and opposite. If the earth pulls him with 850 N, then he pulls the earth with 850 n.
The force that an 800N man exerts on the Earth is equal in magnitude but opposite in direction to the force that the Earth exerts on the man, by Newton's third law. So, the force the man exerts on the Earth is 800N.
The Earth has a higher mass, which means it exerts a larger gravitational force.
Anything that has mass exerts a gravitational field, so yes, earth exerts one.
The answer is gravitational attraction. It is the attractive force between all objects that have mass. It's between you and me, you and your PC, and between everything.
While the ball does exert a force on Earth according to Newton's third law of motion, the force exerted by the ball on Earth is much smaller compared to the force exerted by Earth on the ball due to Earth's much larger mass. This makes the effect of the ball's force on Earth negligible in comparison.
Earth has a mass that exerts a gravitational force, pulling objects towards its center. This force is what causes objects to fall towards the ground when dropped. The strength of the gravitational pull depends on the mass of the objects and the distance between them and Earth's center.
Though the Moon is much smaller than the Sun, it is closer to Earth than the Sun. So exerts a greater gravitation effect on Earth's oceans and seas.
The earth exerts a stronger gravitational force.
